Given below are two statements : One is labelled as Assertion $A$ and the other is labelled as Reason R
Assertion A : Two metallic spheres are charged to the same potential One of them is hollow and another is solid, and both have the same radii Solid sphere will have lower charge than the hollow one
Reason R : Capacitance of metallic spheres depend on the radii of spheres
In the light of the above statements, choose the correct answer from the options given belows
