Two equally charged particles are held 3.1 x 10-3 m apart and then released from rest. The initial acceleration of the first particle is observed to be 8.0 m/s2 and that of the second to be 9.0 m/s2. The mass of the first particle is 6.3 multiplied by 10-7 kg.
(a) What is the mass of the second particle?(b) What is the magnitude of the charge of each particle?
