Question

The value of surface tension is 80 dyne/em. What will be its value in Nm-​

Answer 1

we know that

$1000 \frac{dyne}{cm} = 1 \frac{newton}{m}$

then

1 dyne /cm = 10^_3 n/m

⏩ 80 dyne/cm = 0.08 n/ m

the value of surface tension is 80 dyne/ cm

then it is in Newton /metre is ,0.08

I hope it help you ❤️
