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

Options

A. `3.5xx10^(-2)N`
B. `3.5xx10^(-3)N`
C. `3.5xx10^(-1)N`
D. `3.5xx10^(-4)N`

Answer

A

Explanation

Force due to S.T`=` weight
`(2)/(T)=` weight `implies2xx30xx10^(-3)xxT=3.5xx10^(-3)` Same liquid, same temperature same length of the film supports same weight.
