An electric charge q is placed on an isolated metal sphere of radius r₁.If an uncharged sphere of radius r₂ (with r₂ > r₁)is then connected to the first sphere,the spheres will have equal

Quizplus · Accepted Answer

When the uncharged sphere is connected to the charged sphere, the charges will move to distribute themselves uniformly over the surfaces of both spheres. Since the two spheres are now in contact, their potentials will become equal as they will have reached electrostatic equilibrium. Therefore, the correct choice is C- the potentials will be equal. The charge distribution will cause the charged sphere to have a total charge Q and the uncharged sphere to have a charge -Q. Since both spheres are metallic, their potentials will be equal in the electrostatic equilibrium state.
