Question

Assertion (A): It is not necessary that a force always causes displacement of the body in its own direction.

Reason (R): The work done depends on (i) the magnitude of force, (ii) magnitude of displacement and (iii) the angle between the force and displacement.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correction explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

Explanation:

Work depends on the angle between force and displacement, so a force need not act in the direction of the displacement.
