- 1) What must be the distance between point charge Q1 = 26.0 µC and point charge
- Q2 = -47.0 µC for the electrostatic force between them to have a magnitude of
- 5.70 N?
- [ d= 1.39 m]

- Two particles are fixed on an x axis. Particle 1 of charge 50 µC is located at x = -2.0 cm; particle 2 of charge Q is located at x = 3.0 cm. Particle 3 of charge magnitude 20 µC is released from rest on the y axis at y = 2.0 cm. What is the value of Q if the initial acceleration of particle 3 is in the positive direction of (a) the x axis and (b) the y axis (solution is not given)?
- x-axis. no net force on the y-axis
