Question

In a gravity free space, the liquid in a capillary tube will rise to 

(A) the same height as that on the Earth 

(B) a lesser height than on the Earth 

(C) slightly more height than that on the Earth 

(D) the top and overflow.

Answer 1

Correct Option is (D) the top and overflow.

In a graviy free space there will no force to balance surface tension . So liquid will over flow.

Surface \(F_T = W\)

\(\because W = mg\)   ...... W = weight

g = 0

\(F_T = 0\)

\(F_T\) = Force due to surface tension

Answer 2

(D) the top and overflow.
