Solution

The correct option is C
Changing both magnitude and direction.

Let us consider an example of throwing a stone. The magnitude of the force applied in throwing the stone decides how far the stone will go, but the direction depends on the direction of force. If the magnitude or direction of the force is changed, the stone will go to the different location. Thus, changing either its magnitude or its direction can change the effect of force.

Observation 1: Try to stop a ball coming towards you,so as to save a boundary, by applying a force of some magnitude in the opposite direction of the motion of ball.

Observation 2: In this case apply the force of same magnitude but in same direction of the motion of the ball.

In observation 1 boy saves a boundary by applying a force opposite to the direction of motion but in observation 2, the change in direction of force cost the team 4 runs as the change in direction of force pushed the ball further to the boundary.

So, the change in effect of a force can be experienced by a change in it's direction as well as magnitude. The above statement is :-
