Two objects A and B are thrown upward simultaneously with the same speed.
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.

(b) A will go higher than B.
Explanation:
The force of resistance of air will add to retardation of both the body but its magnitude will depend upon mass of the objects as per "Newton's Second Law of Motion" and it will be equal to Force/mass. Since the force is equal on both the objects, the object having greater mass (A) will be retarded less, so it will go higher than B.
