Question

Two identical metallic sphere of equal mass are taken. One of them is given negative charge and the other is charged positively. Would there be any difference in mass? If yes, then why?

Answer 1

Explanation:

both the sphere are identical

so, initially mass of both the sphere had same mass

but 1 sphere is charged negatively possibly by giving electron .

and another sphere is positively charged by giving protons.

mass of electron > protons

so negatively charged sphere has more mass

if both sphere are charged by induction separately then their mass will be same
