The spherical liquid bubble of diameter ...

The spherical liquid bubble of diameter ` 4 xx 10^(-3)` m has inner and outer pressure as 1.005 and tension of the lquid of the liquid is

A

250 N/m

B

25N/m

C

`2.5`N/m

D

`0.25` N/m

Text Solution

Verified by Experts

The correct Answer is:
D
` P = P_(0) + (4T )/r " " :. (4T)/r= P- P_(0)`
` T = (0.005 xx 105 xx 2 xx 10^(-3))/4 = 0.25 `N/m ,
