1) A particle of charge +2.56 x 10-6 C is 12.4 cm distant from a second particle of charge -1.55 x 10-6 C. Calculate the magnitude of the electrostatic force between the particles.

2) Two equally charged particles, held 4.1 x 10-3 m apart, are released from rest. The initial acceleration of the first particle is observed to be 6.7 m/s2 and that of the second to be 13 m/s2. If the mass of the first particle is 6.7 x 10-7 kg, what are

(a) the mass of the second particle and

(b) the magnitude of the charge (in C) of each particle?

3) Three particles are fixed on an x axis. Particle 1 of charge q1 is at x = -a and particle 2 of charge q2 is at x = +a. If their net electrostatic force on particle 3 of charge Q is to be zero, what must be the ratio q1/q2 when particle 3 is at (a) x = +0.722a and (b) x = +1.87a?
