While measuring surface tension of water using capillary
rise method, height of the lower meniscus from free
surface of water is 3 cm while inner radius of capillary tube is found to be 0.5 cm. Then, compute tension of
water using this data (take, contact angle between glass
and water as

0

and

g = 9.81 \text{m/s}^2)

View answer and explanation

Correct option: B

0.77 N/m

Option B (0.77 N/m) is correct because it is the surface tension calculated using the capillary rise method formula with the given values.
