Two particles, with identical positive charges and a separation of 2.60 × 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a→1 whose magnitude is 4.60 × 103 m/s2, while particle 2 has an acceleration a→2 whose magnitude is 8.50 ×103 m/s2. Particle 1 has a mass of 6.00 × 10-6 kg. Find

(a) The charge on each particle and

(b) The mass of particle 2.
