A charge is placed on a spherical conductor of radius r1.This sphere is then connected to a distant sphere of radius r2 (not equal to r1) by a conducting wire.After the charges on the spheres are in equilibrium:

Question

Quizplus · Accepted Answer

When the two spheres are connected by a conducting wire, they will reach the same potential. This is because charges will flow between the spheres until the potential difference between them is zero. The electric fields at the surfaces of the spheres may not be equal since they depend on the distribution of charges, which could differ between the two spheres. The amount of charge on each sphere cannot be determined without knowing the initial charge and the resistances of the conducting wire and the spheres. The potentials are not in ratio of any specific numbers.
