Two objects A and B are thrown upward simultaeously with the same speed. The mass oif A is greater than the mass of B. Suose the ir exerts a constant and equal force of resitance on the two bodies.
a.The two bodies will rech 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

Answers & Comments
Answer:
Answer. (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.

Explanation:
A will get higher.
Because the mass of A is higher and the forces of resistance are said to be equal…
Without resistance forces the maximum height would be equal, but, with resistance have a force pointing downwards and F=m×a… so, for an equal resistance force, if the mass is higher the acceleration is lower, if the mass is lower, the acceleration is higher. The body B with a higher downwards acceleration gets stopped sooner and can’t get as high as body A
