A solid conducting sphere holds more charge than a hollow sphere of the same radius when they are at same potential.

Assertion : A solid sphere and a hollow sphere both of same material are immersed in a liquid , then change in weight in both the spheres will be same. Reason : Upthrust depends upon the volume of the solid immersed not the mass.
