Question

Why does the spheres move towards each other

Answer 1

Answer:

The charges are induced in sphere as shown in above figure. Since distance between the negative induced charge and positive charge decreases, force increases and thus it keeps moving towards the positive charge.

Electric forces are conservative so total energy doesn't change, and since kinetic energy is increasing, potential energy must decrease.

Answer 2

Answer:

Distance between the negative induced in sphere and positive induced decreases, Force increases, and thus it keeps moving towards the positive charge. Electric forces are conservative so total energy doesn't change, and since kinetic energy is increasing and potential energy must decrease
