Question

Two capillary tubes of radii \(r_1\) and \(r_2\) \((r_1 > r_2)\) are dipped vertically in the same liquid. The rise of liquid in the tubes \(h_1\) and \(h_2\) satisfies:

• A. \(h_1 > h_2\)
• B. \(h_1 < h_2\)
• C. \(h_1 = h_2\)
• D. \(h_1 r_2 = h_2 r_1\)

Hint:

Remember: "Thinner tubes draw higher columns." The narrower the capillary bore, the higher the liquid column must ascend to balance the upward surface tension force against gravity.

Answer 1

The Correct Option is B
