A mosquito with 8 legs stands on water surface and each leg makes depression of radius a. If the surface tension and angle of contact are T and zero respectively , then the weight of mosquito is

A

8T.a

B

`16 pi Ta`

C

`(Ta)/8`

D

`(Ta)/(16 pi)`

Text Solution

Verified by Experts

The correct Answer is:
B
Figure shows one of the legs of the mosquito landing upon the water surface.
Therefore, `T.2piaxx8=W`=weight of the mosquito
