Two equally charged particles are held3.2x10 -3 m apart and then released from rest. The initial acceleration of the first particle isobserved to be 7.0 m/s 2 and that of the second tobe 9.0m/s 2 . If the mass of the first particle is 6.3x 10 -7 kg, what are
(a) the mass of the second particle and
(b) the magnitude of the charge ofeach particle?
