Assertion (A): | If two particles move with uniform accelerations in different directions, then their relative velocity changes in direction. |
Reason (R): | Since the acceleration are in different directions, there is a relative acceleration and hence the relative velocity changes. |
1. | (A) is True but (R) is False. |
2. | (A) is False but (R) is True. |
3. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
4. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
Assertion (A): | The relative velocity between any two bodies may be equal to the sum of the speeds of the two bodies. |
Reason (R): | Sometimes, the relative velocity between two bodies may be equal to the difference in the speeds of the two. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
