What is the charge on sphere B?
+20e Initially, sphere A has charge of −50e and sphere B has a charge of +20e. The spheres are made of conducting material and are identical in size. If the spheres touch each other, what is the resulting charge on sphere A?
What is the final charge on each sphere?
The spheres are brought together, allowed to touch, and then separated. What is the net charge on each sphere now? When the spheres are touched the net +4Q charge will spread out evenly over the two spheres. Each sphere will have a net charge of +2Q.
How do you find a new charge on a sphere?
We need to know the charge on each sphere, we have been given one. As the spheres are identical in material, size and shape the charge will redistribute across the two spheres so that it is shared evenly. Each sphere will have half of the total charge: Q=Q1+Q22x=9,6×10−18+(−9,6×10−18)2x=0C.
What is the total charge in C of the sphere?
The final charge on sphere C is −5.625q .

How do you find the charge of an object?
The quantity of charge on an object reflects the amount of imbalance between electrons and protons on that object. Thus, to determine the total charge of a positively charged object (an object with an excess of protons), one must subtract the total number of electrons from the total number of protons.
What is the total charge on the three spheres after they have touched?
Yes. The conservation of electric charge states that, during any process, the net electric charge of an isolated system remains constant (is conserved). Therefore, the net charge on the three spheres before they touch (–12.0 mC + 4.0 mC + 2.0 mC = –6.0 mC) is the same as the net charge after they touch.

How do you calculate the charge on each sphere after they have separated?
1 Answer
- n = Q/e. 30 = Q/(-1.6×10^-19) Q = -4,8 x 10^-18 C.
- Unlike or opposite charges attract.
- The net or total charge in an isolated/closed system remains constant/is conserved.
- Qnet= (Q1+Q2)/2.
What is charge and current?
Current: It is the rate of flow of charge (generally electrons). Current (I) is the physical quantity measured in amperes (A). Charge: It is the deficiency or excess of electrons on a body surface. Charge (Q) is the physical property of matter measured in Coulombs (C).
What is total charge of an atom?
The total electric charge of the atom is therefore zero and the atom is said to be neutral. In contrast, when an atom loses or gains an electron (or the rarer case of losing or gaining a proton, which requires a nuclear reaction), the total charges add up to something other than zero.

What is the negative charge?
negative charge in British English (ˈnɛɡətɪv tʃɑːdʒ ) physics. a charge that has more electrons than protons and has a lower electrical potential.
What is the total charge of the three spheres before and after touching each other?
Yes. The conservation of electric charge states that, during any process, the net electric charge of an isolated system remains constant (is conserved). Therefore, the net charge on the three spheres before they touch (–12.0 mC + 4.0 mC + 2.0 mC = –6.0 mC) is the same as the net charge after they touch.
How is final charge calculated?
You can also use Ohm's law (V = IR) to calculate current from voltage and resistance. For a circuit with voltage 3 V and resistance 5 Ω that is applied for 10 seconds, the corresponding current that results is I = V / R = 3 V / 5 Ω = 0.6 A, and the total charge would be Q = It = 0.6 A × 10 s = 6 C.

What is the charge of 1 electron?
electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb.
How do you calculate net charge gained or lost?
The Net Charge is determined by the excess or extra number of charges that it has gained/lost. where q (could also be Q) represents the Net Charge, n is the extra number of protons/electrons, and e represents the "Elementary Charge"; the amount of charge of 1 p, or 1 e-.

What is the positive charge?
A positive charge occurs when the number of protons exceeds the number of electrons. A positive charge may be created by adding protons to an atom or object with a neutral charge. A positive charge also can be created by removing electrons from a neutrally charged object.
What has a positive charge?
Protons are positively charged and neutrons and neutral. Charged particles are called ions. These are formed when an atom loses or gains valence electrons. Positively charged ions are known as cations and negatively charged ions are known as anions.
What is the final charge on each sphere when the two charges are brought into contact?
When the two conducting spheres are brought together to touch, it is as though they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres. When the spheres are moved apart again, each one is left with half of the total original charge.
How do you find the total charge?
To calculate the total charge on an object we multiply the constant value of e by the number of electrons deposited on (or removed from) an object.

To calculate the total charge on an object we multiply the constant value of e by the number of electrons deposited on (or removed from) an object.
What is the charge on all atoms?
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
Which particle has a charge of +1?
Protons Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
Is an electron a negative charge?
Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges.
