trying to study but stuck on this problem.

Two particles, with identical positive charges and a separation of 2.34 x 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 6.75 x 103 m/s2, while particle 2 has an acceleration a2 whose magnitude is 11.3 x 103 m/s2. Particle 1 has a mass of 6.35 x 10-6 kg. Find (a) the charge on each particle and (b) the mass of particle 2.
