Q1. Two particles are fixed on an x axis. Particle 1 of charge 51.50 μC is located at x = -33.2 cm; particle 2 of charge Q is located at x = 10.10 cm. Particle 3 of charge magnitude 37.7 μC is released from rest on the y axis at y = 11.30 cm. What is the value of Q if the initial acceleration of particle 3 is in positive direction of (x axis and (b) y axis?
Give the answers in μC.
Q2. A dog's hair has been cut and is now getting longer by 1.04 mm each day. With winter coming on, this rate of hair growth is steadily increasing, by 0.132 mm/day every week. By how much will the dog's hair grow during 5 weeks?
