A liquid is filled into a semi elliptical cross section with a as semi major axis and b as semi minor axis. The ratio of surface tension forces on the curved part and the plane part of the tube in vertical position will be

A

`(pi(a+b))/(4b)`

B

`(2pia)/(b)`

C

`(pia)/(4b)`

D

`(pi(a-b))/(4b)`

Text Solution

Verified by Experts

The correct Answer is:
A
`F_(1)=Txx(pi(a+b))/(2)," "F_(2)=Txx(2b)`
`(F_(1))/(F_(2))=(pi(a+b))/(4b)`
