Two copper spheres of same radius ,one hollow and other solid are changed to same potential . Which will have more charge

Question

Arun · Answer

Dear student

The capacitance of a charged sphere whose radius is r is given by:
C = 4*ε0*pi*r
As the capacitance of a spherical body (copper) depends only on the radius and independent of mass, both a hollow sphere and a solid sphere of copper having same radii will have the same capacitance. So, both of them will have same charge.
