Two particles, with identical positive charges and separation of 2.55 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration vector a1 whose magnitude is 4.65 103 m/s2, while particle 2 has an acceleration vector a2 whose magnitude is 8.55 103 m/s2. Particle 1 has a mass of 6.05 10-6 kg.
a. Find the charge on each particle. q1 = C q2 = C
b. Find the mass of particle 2. kg
