Two equally charged particles are held 3.0 10-3 m apart and then released from rest. The initial acceleration of the first particle is observed to be 5.0 m/s2 and that of the second to be 10.0 m/s2. The mass of the first particle is 6.3 10-7 kg.
(a) What is the mass of the second particle?
(b) What is the magnitude of the charge of each particle?
