Chapter 22, Problem 22.6(choose chapter or problem)
In the discussion concerning Figure 22.5, we saw that a force of 0.086 N from an external agent was required to keep the rod moving at a constant velocity. Suppose that friction is absent and that the light bulb is suddenly removed from its socket while the rod is moving. How much force does the external agent then need to apply to the rod to keep it moving at a constant velocity? (a) 0 N (b) Greater than 0 N but less than 0.086 N (c) More than 0.086 N (d) 0.086 N
