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

Laws of Motion Report Error

A

The two bodies will reach the same height

B

will go higher that

C

will go higher than

D

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

Solution:

If mass of is higher then its acceleration due to gravity is and due to air friction is so net acceleration of in upward motion is - which is less compared to that of as its mass is higher so it will ascend more height than .
