Assertion (A): | When height of a tube is less than liquid rise in the capillary tube, the liquid does not overflow. |
Reason (R): | Product of radius of meniscus and height of liquid in capillary tube always remains constant. |
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. | (A) is False but (R) is True. |
Assertion (A): | Water rises higher in a capillary tube with a small diameter than in the one with a large diameter. |
Reason (R): | The height to which a liquid rises in a capillary tube is inversely proportional to the diameter of the capillary tube. |
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. | (A) is False but (R) is True. |
Assertion (A): | When a capillary tube is dipped into mercury, the mercury level in the tube falls. |
Reason (R): | Mercury is a very viscous liquid. |
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. |
Assertion (A): | A liquid may neither rise nor fall in a capillary tube. |
Reason (R): | This is possible if and only if the surface tension is zero. |
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. |
