Need help please

A small metal sphere, carrying a net charge of q1 = 2.93 UC, is held in place by insulating supports. A second small metal sphere, with a net charge of q2 = 2.06 UC and mass m = 4.25 g, is moving toward the first sphere with a speed v = 15 m/s when the center to center separation is d = 79.8 cm. n 91 92 What is the closest center to center separation of q1 and q2, shown on the picture as n.? Assume that the two spheres can be treated as point charges and that you can ignore the effects of gravitational attraction between the spheres. Give your answer in units of cm
