Two blocks hang from strings would around different parts of a 2 kg double pulley as shown. The pivot exerts a normal force FN supporting the double pulley. Assuming the system is not in equilibrium, which statement about FN is true after the system is released from rest? (Use g = 10 N/kg.)
 
  1.FN = 20 N
  2.20 N < FN < 27 N
  3.FN = 27 N
  4.FN > 27N
  5.It is impossible to predict what the normal force on the double pulley will be.

Question 2

Two blocks hang from strings wound around different parts of a double pulley as shown. Assuming the system is not in equilibrium, what happens to the system's potential energy when it is released from rest?
 
  1.It remains the same.
  2.It decreases.
  3.It increases.
  4.Impossible to determine without knowing the radii of the two pulleys.
  5.Impossible to determine without knowing the ratio of the radii of the two pulleys.
  6.Impossible to determine for some other reason.
