Question

Two particles, with identical positive charges and a separation of 3.40 × 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 3.55 × 103 m/s2, while particle 2 has an acceleration a2 whose magnitude is 9.33 × 103 m/s2. Particle 1 has a mass of 6.93 × 10-6 kg. Find (a) the charge on each particle and (b) the mass of particle 2.

Answer 1

D = 3.4 times 10^-2 m electric force F = k q_1 q_2/d^2 {here q_1 = q_2 = q F = m_1 a_1 = m_2 a_2 m_1 a_1 = k q^2/d^2 6.93 times 10^-6 times 3.55 times 10^3 = 9 times 10^9 times q^2/(3.4 times 10^-2)^2 q^2 = 0.236 times 10^-16 C^2 q = 0.48 times 10^-8 C Answer -a m_2 = 6.93 times 10^-6 times 3.55 times 10^3/9.33 times 10^3 m_2 = 2.63 times 10^-6 kg
