Two identical conducting spheres are placed with their centers 0.24 m apart. One is given a charge of 6 10-9.

Question

The spheres are connected by a conducting wire. Find the electrostatic force between the two, after equilibrium is reached.

Answer 1

When the spheres are connected, the charges will distribute equally to both spheres. Therefore each sphere will end up with a charge of 3*10^-9 coul. The force will be repulsive and equal to [3*10^-9]^2 / 4*π*e0 (Coulomb's law)
