## Homework Statement

Q2. Two particles, with identical positive charges and a separation of 3.80 x 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 6.71 x 103 m/s2, while particle 2 has an acceleration a2 whose magnitude is 9.64 x 103 m/s2. Particle 1 has a mass of 7.46 x 10-6 kg. Find (a) the charge on each particle and (b) the mass of particle 2.
