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, 2 2 0 1 4 eq mv rr ε = π so () ( ) 2 27 5 2 9 0 92 2 9 1.67 10 kg 3.00 10 m/s 0.0100 m 4 1.04 10 C. 8.99 10 N m / C
