Question

An isolated 4.1 cm radius spherical conductor has a total charge of 21 nC. It is connected to another conducting sphere with a radius of 7.1 cm, initially discharged, by means of a long conducting wire. After a sufficient amount of time for the charges to be distributed on the two conductors, what is the potential difference in the second sphere?

Answer #1

this is the potential on the second sphere.

But you have asked for potential difference on second sphere which is invalid. Bcz potential difference happens between 2 different spheres not only on a single sphere.

In case If you were asking for potential difference between the two spheres then the answer will be 973.89 volts. (By doing,

Potential of sphere 1 - potential of sphere 2)

Thanks.
