What is the electric field just outside the sphere?
Electric Field: Sphere of Uniform Charge The electric flux is then just the electric field times the area of the spherical surface. The electric field outside the sphere (r > R)is seen to be identical to that of a point charge Q at the center of the sphere.
What is the density of the charge in the hollow sphere?
A hollow, conducting sphere with an outer radius of 0.253 m and an inner radius of 0.194 m has a uniform surface charge density of 6.96 × 10-6 C/m2.
What is the charge on the sphere?
As there is no electric field inside a conductor , if we assume any hypothetical surface inside a conductor , the net flux φ will be zero. Thus, the net charge inside a conductor Σq = 0. Thus , if +q charge is given to a solid sphere, it will be distributed equally throughout the surface of the sphere .
What are the surface charge densities on the inside and the outside surfaces of the outer conductor?
(a) Since the electric field inside a conductor must be zero, the charge must all reside on the outer surface. The linear charge density on the inner surface is zero and on the outer surface it is +1.

How do you find the electric field outside the spherical shell?
Electric Field outside the Spherical Shell
- ϕ=qε0.
- E×4πr2=σ×4πR3ε0.

How do you find the charge on the surface of a sphere?
- Surface charge density of a conductor is defined as the amount of charge distributed per unit surface area of the conductor. It is denoted by the Greek letter sigma ( σ). …
- Surface charge density, σ = 0.7 C/m2
- Thus, the total charge on the surface of the sphere is, Q = σA.

What is the surface charge density?
Surface charge density (σ) is the quantity of charge per unit area, measured in coulombs per square meter (C⋅m−2), at any point on a surface charge distribution on a two dimensional surface.
How do you find charge density?
- Charge density can be measured in terms of length, area, or volume depending on the body's dimension. …
- The formula of linear charge density is λ=q/l, such that q is the charge and l is the length of the body over which the charge is distributed.
What is the charge on the outer surface of the conducting shell?
The net charge inside the conducting shell is zero so the induced charge on the inner surface of shell is −3Q and also same but opposite charge induced on the outer surface i.e +3Q.
What is the charge on the outer surface of the outer shell?
The net charge inside the conducting shell is zero so the induced charge on the inner surface of shell is −3Q and also same but opposite charge induced on the outer surface i.e +3Q.
What is the surface charge density on the inner surface of the conductor?
Since the Electric field vanishes everywhere inside the volume of a good conductor, its value is zero everywhere on the Gaussian surface we have considered. So the surface integral is zero. This is the total charge induced on the inner surface.
What is the net charge on the outer surface of the shell?
+Q1 + Q2 * The electric field inside the conducting shell is zero. (B) There can be no net charge inside the conductor, therefore the inner surface of the shell must carry a net charge of -Q1, and the outer surface must carry the charge +Q1 + Q2, so that the net charge on the shell equals Q2.
How do you find the charge density of a sphere?
Let a conducting sphere of radius r contains total charge Q on its surface. Now, the surface area of the sphere is A=4πr2. So, the surface charge density is σ = Q 4 π r 2 small {color{Blue} sigma =frac{Q}{4pi r^{2}}} σ=4πr2Q. This is the formula for surface charge density of a sphere.
Why is the charge inside a sphere 0?
All the charges lie on the surface of the charged sphere. If a gaussian surface is drawn within the sphere, there will not be any charge within the surface. Therefore, the electric field strength inside a sphere is zero.
How do you find the electric field at the surface of a sphere?
“Thus the field at the surface of the shell is exactly the same as though all the charge Q were located at the center of the sphere defined by the shell.” Therefore, the strength of the electric field at the surface should be kQ/R2.
What is the surface charge density of the surface?
Surface Charge Density is the amount of charge per unit of a two-dimensional surface area. It is a measure of how much quantity of electric charge is accumulated over a surface. It is expressed by the symbol σ and the unit in the SI system is Coulombs per square meter i.e Cm–2.
