Q. 10

Two objects A and B are thrown upward simultaneously with the same speed. The mass of A is greater than the mass of B. Suppose the air exerts a constant and equal force of resistance on the two bodies.
A. The two bodies will reach the same height.

B. A will go higher than B.

C. B will go higher than A.

D. Any of the above three may happen depending on the speed with which the objects are thrown.

Answer :

the objects are thrown vertically upward, the net force acting on the bodies only due to gravity and the acceleration due to gravity is independent mass of the body since it acts on the individual points of the body. Thus, both the bodies will move to the same height given resistance due to air is same for both. Option A is correct.
