Question
1. Refer to Figure 1. If object B is initially held so that it is above A, as shown, so that neither object can move, what would be the subsequent motions of both objects after they are released? Explain. Do not use algebra.
2. Refer to Figure 2. What would happen to object C when it is released? How will the motion of object C compare to the motion of object A? Explain without algebra.
3. Refer to Figure 2. After C is released, how does the force exerted on object C by the string compare to the weight of C? Is it greater than, less than or equal? Explain.
4. Refer to Figure 2. After C is released how does the force exerted on object A by the string compare to the weight of A? Is it greater than, less than or equal? Explain.
5. Refer to Figure 2. How does the net force on object A compare to the net force on object C? Is it greater than, less than or equal? Explain.

1. When A and B both are released, due to the same mass the tesion in the rope is also equal. Since the equilibrium of forces balances each other so no unbalanced forces exists. When no unbalanced force exists there is no motion occur in body A as well as B.
2.when object c is released due its gravitational force(weight) the tension applied in the strings is high enough to lift the object A with the same acceleration as the body C moves downward.
3. The force exerted by the string(tension) on C is smaller than the weight of C because the acceleration get by C is correspondent to the difference of these two forces.
4.for A the tension in the string is quite high than its weight
5. As the net acceleration produce in both the masses is equal so the magnitude of the net force depends totally on the mass of the object and it's given that the object C is heavier than A, so the net force of C is higher than A.
