In Fig(i) a thin film supports a small weight `3.5xx10^(-2)N` The weight supported by a film of the same liquid at the same temperature in fig.(ii) is

A

`3.5xx10^(-2)N`

B

`3.5xx10^(-3)N`

C

`3.5xx10^(-1)N`

D

`3.5xx10^(-4)N`

Text Solution

Verified by Experts

The correct Answer is:
A
`"Force due to S.T."="Weight"`
`2//L="weight"rArr 2xx30xx10^(-3)xxT=3.5xx10^(-3)`
same liquid, same temperature, same length of the film. Support same weight.
