39. The proton is in uniform circular motion, with the electrical force of the sphere on the proton providing the centripetal force. According to Newton’s second law, F = mv 2 /r ,where F is the magnitude of the force, v is the speed of the proton, and r is the radius of its orbit, essentially the same as the radius of the sphere. The magnitude of the force on the proton is F = eq/ 4 πε 0 r 2 q is the magnitude of the charge on the sphere. Thus, 1 4 0 eq r 2 = mv
