Question

Two copper spheres of the same radii, one hollow and the other solid, are charged to the same potential, then

• A. hollow sphere holds more charge
• B. solid sphere holds more charge
• C. both hold equal charge
• D. we cant say

Answer 1

Answer: (C)

both hold equal charge

We know that the charges reside on the surface of a conductor. Here the two copper spheres are two conductors. So the charge uniformly distributed on the surface on the both sphere. We know that potential at the surface is $V=kq/R.$ As the both spheres have same radius and charged to same potential so they will have equal charge.
