Question

Which of the following statements is/are true?

• A. Forces in same direction will be added.
• B. Two forces in opposite direction result in a net force equal to their difference in the direction of larger force.
• C. Change in either direction or magnitude of force changes its effect.
• D. When more than one force is acting on it, the effect on the object is due to the net force acting on it.

Answer 1

Answer: (A), (B), (C), (D)

When more than one force is acting on it, the effect on the object is due to the net force acting on it.

1. When you and your friend push a box in the same direction, the force applied by both of you adds up to provide the required force.
2. When you and your friend apply opposite forces, it becomes difficult to push the box because the forces applied by both of you cancel each other out, i.e. the net force is the difference between the forces applied by both of you.
3. Furthermore, the box moves in the direction of the greater magnitude of force.
4. When a batsman hits a ball, the direction and magnitude of force applied by the batsman determine the movement of the ball.
5. When multiple forces act on an object, they combine to form a net force. The net force is the sum of all the forces acting on an object. When two equal-strength forces act in opposite directions on an object, the forces cancel, resulting in a net force of zero and no movement.
6. As a result, the effect of a force is affected by both its direction and magnitude.

Hence, All options are correct.
