A liquid rises to a height of $4 \text{ cm}$ in a capillary tube of radius $r$. If another capillary tube of radius $r/2$ is dipped in the same liquid, the height of liquid rise will be}
Show Hint
Remember, for a given liquid and contact angle, the height of the liquid rise in a capillary tube is inversely proportional to its radius.
