A spherical conductor of radius 2 m is charged to a potential of 120 V. It is now placed inside another hollow spherical conductor of radius 6 m. Calculate the potential of bigger sphere, if the smaller sphere is made to touch the bigger sphere.
Text Solution
Verified by ExpertsThe correct answer is:
D
We have, 
When it is made to touch the bigger sphere, whole charge will transfer to bigger sphere.
Potential of bigger sphere,
