Question

If the electric potential of the inner metal sphere is 10 volt and that of outer shell is 5 volt, then the potential at the centre will be

Answer 1

^_^ ^.^^_^ Logical Question

Final Answer : 10 V

Steps:
1) We know that Potential of inner metal sphere is 10 V.
Since, Electric Field in the inner sphere is 0 .
Therefore, Change in potential from surface to centre is 0 .
=> V(surface) - V(centre) = 0
=> 10 V - V(centre)= 0
=> V(centre) = 10 V.

Hence, Potential at centre is 10 V.

^_^Interesting Part :
Potential at centre is independent of Potential of outer sphere. >_<

Answer 2

answer is 10 volt as there is no change in potential inside sphere.
