What is the direction of the electric field at point?
The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.
How do you find the strength of an electric field at a point?
The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.
What is the direction of the electric field at a point directly to the left of a positive charge?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
Where is electric field strength the strongest?
The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
What are the strength and direction of an electric field that will balance the weight of an electron?
(a) The strength of the field is 1.0 ⋅ 1 0 − 7 1.0cdot10^{-7} 1.0⋅10−7 N/C and the field is directed upwards. (b) The strength of the field is 5.6 ⋅ 1 0 − 11 5.6cdot10^{-11} 5.6⋅10−11 N/C and the field is directed downwards.
How do you find the magnitude and direction of an electric field?
We can use the equation E = k | Q | r 2 E = k | Q | r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case. E = k | Q | r 2 = ( 8.99 × 10 9 N ⋅ m 2 /C 2 ) | − 1.5 × 10 − 9 C | ( 0.035 m ) 2 = 1.1 × 10 4 N/C.
At which point is the electric field strongest?
The magnitude of an electric field is directly proportional to the density of electric field lines. When the lines are closer to each other, the >electric field is the strongest; when the filed lines are far apart from each other, the electric field is the weakest.
Why the direction of electric field is from positive to negative?
A field line is defined as a line that is always tangent to the field, and is oriented by the field. Since the electrostatic field is always directed away from positive charges and toward negative charges, field lines must go away from positive charges and toward negative ones.
How can you increase the strength of an electric field?

What are the magnitude and direction of the electric field at point P?
The electric field at point P caused by each charge is equal in magnitude, and both electric fields are in the same direction. are equal in magnitude and the same distance from the origin.
What is the direction of the electric field at a point directly to the left of a positive charge q?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
Which of the following is true for the direction of an electric field?
Which of the following is true for the direction of an electric field? It is same as the direction of the force exerted on a positive test charge.
Where is an electric field the strongest?
The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
What are the strength and direction of the electric field that will balance the weight of a proton?
Being q=−1 for the electron and q=+1 for the proton. You can consider that g is a vector pointing downwards, so E for the electron will point downwards and for the proton it will point upwards.
What are the magnitude and direction of the electric field at the centre of the square?
Physics The direction of electric field at the centre of the square is parallel to side. Q.
What is the relationship between the density of the electric field lines and the strength of the electric field?
The electric field is inversely proportional to the square root of density of electric field lines.
What influences the strength of an electric field?
Strength of an electric field is affected by the distance from the charge and the amount of charge that produces the field.
What is the magnitude of an electric field that will balance the weight of an electron?
Q. What is the magnitude of electric field intensity that balances the weight of an electron.It is given that e=1.6×10−19C and me=9.1×10−31kg.
What does electric field depend on?
The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.
How do you find the magnitude and the direction of the electric field?
We can use the equation E = k | Q | r 2 E = k | Q | r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case.

What is magnitude and direction?
Magnitude answers “how much?” and direction answers “which way?”. For example, 5 meters is a magnitude, North is a direction. 5 meters north is a vector quantity, which has both magnitude and direction.
How do you determine the direction of an electric field from a magnetic field?
To find the direction of propagation of an E&M wave, point the fingers of the right hand in the direction of the electric field, curl them toward the direction of the magnetic field, and your thumb will point in the direction of propagation.
What is the direction of the electrostatic force on a proton in an electric field?
The force acts in the same direction as that of the electric field, when the charge is positive and the opposite direction when the charge is negative.
