A soap bubble of radius `10^(-2)` m is formed . The surface tension of the soap bubble is 0.04 N/m The excess of pressure inside the bubble is

A

`160 N//m^(2)`

B

`16 N//m^(2)`

C

`1.6 N//m^(2)`

D

`0.16 N//m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
` P = (4T)/r = (4 xx 0.04 )/(10^(-2)) = 16 " N/m"^(2)`
