Question
The upward muscular and the downward gravitational forces acting on a ball thrown up are shown in the figure below. What is the net force on the ball, and in which direction does it act?
- 52 N, downward
- 52 N, upward
- 22 N, downward
- 22 N, upward
Hint:
22N, downward
The correct answer is: 22 N, downward
- Here, the applied force on ball is in upwards direction of magnitude 15 N.
- And the opposing gravitational force is 37 N.
- Hence, to find the net force of two opposing force will be subtraction of two given force which will be equal to 22 N.
- Ball will tend to move towards the force which is greater that means ball will move towards the direction of gravitation pull or we can say that it will move downward.
