Two equally charged particles are held 3.2*10^-3m apart and then released from rest. The initial acceleration of the first particle is observed to be 7m/s^2 and that of the second to be 9m/s^2. If the mass of the first particle is 6.3*10^-7kg, what are
a) The mass of the second particle and
b) The magnitude of the charge of each particle?
