Question
A conducting spherical shell of radius 1m ischarged upto potential of 10.volt. Anotherconducting spherical shell of radius 2 m is chargedupto potential of 10 volt. Now smaller sphere isplaced inside the bigger sphere by insulatinghandle and connect them by a conducting wireNo flow to charge between the spheres asame potentialPotential of outer sphere will become 15 volt(3) Potential of inner sphere will become 6 volt(4) Both (2) & (3)
