Question

The electric field at a distance 3R/2 from the centre of a charged conducting spherical shell of radius R is E. The electric field at a distance R/2 from the centre of the sphere is:

G1 Physics · Accepted Answer

Step 1: In electrostatic equilibrium charge on a conductor resides on its outer surface. Step 2: The electric field at every point inside a conducting spherical shell (r < R) is zero. Step 3: Since R/2 < R, E(R/2) = 0.
