Assertion (A): For a moving particle on a straight line magnitude of average velocity between any two points will be less than magnitude of instantaneous velocity at every point between them.
Reason (R): In \(x-t\) graph slope of chord joining two points gives average velocity between them.
Solution:
Assertion (A) is false. The magnitude of average velocity can be equal to or greater than the magnitude of instantaneous velocity at some points, or less than at others. For constant velocity, they are equal.
Reason (R) is true. By definition, the slope of the chord in an \(x-t\) graph represents the average velocity. However, since Assertion (A) is false, option (4) is selected.
