71. 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 , where q is the magnitude of the charge on the sphere. Thus,
