Question
A boy throws a cricket ball from the boundary to the wicket-keeper. If the frictional force due to air cannot be ignored, the forces acting on the ball at the position X are respected by
The correct answer is:
The forces acting on the ball will be (i) in the direction opposite to its motion 
frictional force and(ii) weight 
.
