Question

Two particles, with identical positive charges and a separation of 3.82 × 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 5.15 × 103 m/s2, while particle 2 has an acceleration a2 whose magnitude is 11.3 × 103 m/s2. Particle 1 has a mass of 6.31 × 10-6 kg. Find (a) the charge on each particle and (b) the mass of particle 2.

Answer 1

Here, the given two charges are positive, so their coulomb force will be repulsive in nature. Then as soon as the charges will be released they will move away from each other.

Also, this force will cause acceleration of the bodies, which is given by: $F=ma$
