Answer to Question #28615 in Electric Circuits for ali

Question

Two equally charged particles, held 3.2x10-3m apart, are released from rest. The initial acceleration of the first particle is observed to be 7m/s2 and that of the second to be 9m/s2. If the mass of the first particle is 6.3x10-7kg, what are (a) the mass of the second particle and (b) the magnitude of the charge of each particle? Coulomb’s constant = 9x109N.m2/C2
