A nonzero net force acts on a moving ball, and the ball comes to a stop. Which statement is correct about the relationship between the net force and the ball's movement? The net force causes a decrease in acceleration because without the force, the ball's movement would remain the same. An increase in acceleration causes the net force to be nonzero because causation works in both directions. A decrease in acceleration causes the net force to be nonzero because causation works in both directions. The net force causes an increase in acceleration because without the force, the ball's movement would remain the same.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
