2. Spheres A and B have the same initial positive charge q. The magnitude of the repulsive electric force between the two spheres is 14.4 N when separated by a distance of 0.03 m. (a) Find the initial charge q,. (b) The spheres are then allowed to touch each other and then separated. Find the electric force between them if the radius of sphere A is three times that of sphere B.
