Two small equally charged spheres, each of mass m, are suspended from the same point by silk threads of length 1. The distance between the spheres x << 1. Find the rate dqldt with which the charge leaks off each sphere if their approach velocity v = a/ √x, where a is a constant.
The Attempt at a Solution
The net acceleration required=dv/dt=-a^2/(2x^2)
This acceleration is given by electrostatic force and weight of the mass.
Is i take components and get the q and differentiate it the answer comes wrong.
Many solutions say that the body is constantly at equilibrium but i dont understand why.
