A particle with a mass of 3.8 g and a charge of +0.045 μC is released from rest at point A in Figure 20-20. (a) In which direction will this charge move? (b) What speed will it have after moving through a distance of 5.0 cm? The electric field has a magnitude of 1200 N/C. (c) Suppose the particle continues moving for another 5.0 cm. Will its increase in speed for the second 5.0 cm be greater than, less than, or equal to its increase in speed in the first 5.0 cm? Explain.
