1. The magnitude of the electrostatic force between two identical ions that are separated by a distance of 6.5 x 10-10 m is 78.65 x 109 N. (a) What is the charge of each ion? (b) How many electrons are "missing" from each ion (thus giving the ion its charge imbalance)? (a) Number Units (b) Number Units 2. In Figure (a) particles 1 and 2 have charge 45.0 µC each and are held at separation distance d = 2.80 m. (a) What is the magnitude of the electrostatic force on particle 1 due to particle 2? In Figure (b), particle 3 of charge 45.0 µC is positioned so as to complete an equilateral triangle. (b) What is the magnitude of the net electrostatic force on particle 1 due to particles 2 and 3? d 2 (a) (b) (a) Number Units (b) Number Units 3. Two particles are fixed on an x axis. Particle 1 of charge 59.0 µC is located at x = -7.55 cm; particle 2 of charge Q is located at x = 31.4 cm. Particle 3 of charge magnitude 53.7 µC is released from rest on the y axis at y = 7.55 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? (a) Number Units (b) Number Units 4. Two equally charged particles, held 4.3 x 103 m apart, are released from rest. The initial acceleration of the first particle is observed to be 8.0 m/s2 and that of the second to be 11 m/s?. If the mass of the first particle is 8.5 x 10 kg, what are (a) the mass of the second particle and (b) the magnitude of the charge of each particle? (a) Number Units (b) Number Units 1.
