Assertion (A): A ball is dropped from rest. A second ball is dropped from rest from the same height as the first, but 1s later. The distance between the balls when both are moving remains constants.

Question

Assertion (A): A ball is dropped from rest. A second ball is dropped from rest from the same height as the first, but 1s later. The distance between the balls when both are moving remains constants.

Reasons (R): When both the balls are falling freely, the acceleration of one ball with respect to another is zero.

(4)

Since relative acceleration is zero so relative velocity will remain constant and hence separation keeps on increasing.

Solution

1 Assertion and Reason are True; Reason is a correct explanation for Assertion

2 Assertion and Reason are True; Reason is not a correct explanation for Assertion

3 Assertion is True, Reason is False

4 Assertion is False, Reason is True
