Consider the arrangement of pulleys and masses shown below. The masses of the pulleys are small. Ignore friction.

This system is initially at rest. What will happen if the ring R is moved to the right?

  1. Nothing will happen.
  2. Mass M will go up and m will go down.
  3. Mass M will go down and m will go up.
  4. Both masses will go down.
  5. Both masses will go up.
  6. Cannot be determined because what happens depends on the masses.
