1. The problem statement, all variables and given/known data Two spheres have a radius of 1cm each and carries 4.3nC and -9nC each. The two sphere are separated by an unknown distance. If both spheres are connected by a thin wire, what wil be the potential on each once equilibrium is reached? and how much charge must move between the sphere in order to achieve equilibrium? 2. Relevant equations Potential of a point charge: V = kq/r 3. The attempt at a solution The charge on each sphere when they are not connected is 38.7KV, and -8.1KV. I believe that if they are connected and are at equilibrium, the net charge will be zero hence charge at sphere 1 should be equal to charge at sphere 2. Am i right?
