Question

A mosquito with 8 legs stands on water surface

Answer 1

Answer:

this is because the surface tension property of water (any liquid can show).

Explanation:

For this property water act like a stretched membrane.

Answer 2

Force Acting will be Equal to Weight

Explanation:

$F = T \times L$, where

T is the Surface tension and

L is the length on which the force is acting.

Clearly, the Force acting is equal to the Weight of the mosquito

$L = 8 \times 2\pi a$

$F = T \times L$

  = $16 \pi Ta$

Hence, Answer is (b)
