A ball is thrown in upwards direction then the force(s) acting on it is (are)

A

gravitational force

B

mechanical force

C

fictional force

D

Both (a) and (c ).

Text Solution

Verified by Experts

The correct Answer is:
D
When ball is thrown in upward direction, its weight always acts in downward direction and as the body is moving upwards, frictional force (due to air) acts in downward direction.
