Question

If surface tension of a liquid is 5 x 10-2 N/m and weight of the liquid column is 6.28 x 10 Kg. Find
out the radius of the capillary tube?
(A)2x10-m
(B)2.5x10-3m
(C)2x10-m
(D)4x 10-3 m

​

Answer 1

Answer:

ANSWER

Since, Force = T×2πR

So,

6.28×10

−4

=T×2πR

T=

2×π×2×10

−3

6.28×10

−4

T=5×10

−2

N/m
