The surface tension of a liquid is 10^(8...

The surface tension of a liquid is `10^(8)` dyne `cm^(-1)`. It is equivalent to

A

`10^(7)` N/m

B

`10^(6)`N/m

C

`10^(5)`N/m

D

`10^(4)`N/m

Text Solution

Verified by Experts

The correct Answer is:
A
` T = 10^(8) dy//cm^(2) = (10^(8) xx10^(-5))/(10^(-4)) = 10^(-7)`
