Question

Hello people ~
Two copper spheres of the same radius, one solid and the other hollow, are charged to the same potential. Which will have more charge?

(a) Solid sphere

(b) Hollow sphere

(c) Both will have an equal charge

(d) None of these
​

Answer 1

C

Let's see how

We know the rule

$\\ \rm\rightarrowtail V=\dfrac{Kq}{r}$

$\\ \rm\rightarrowtail Kq=vr$

$\\ \rm\rightarrowtail q\propto r$

As radius is same charge will be same in both

Hence they both have same charge
