The surface tension of a liquid is `70 "dyne" // cm` . In MKS system its value is

A

70 N/m

B

`70 xx 10^(-2)`N/m

C

`7xx10^(2)` N/m

D

`7xx10^(3)` N/m

Text Solution

Verified by Experts

The correct Answer is:
B
`T_(w) = 70 dy//cm = (70 xx 10^(-5))/(10^(-2))`
` = 70 xx 10^(-3) = 70 xx 10^(-2)` N/m
