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

Options

A. `(pi(a+b))/(4b)`
B. `(2pia)/(b)`
C. `(pia)/(4b)`
D. `(pi(a-b))/(4b)`

Answer

A

Explanation

`F_(1)=Txx(pi(a+b))/(2),F_(2)=Txx(2b)`
`(F_(1))/(F_(2))=(pi(a+b))/(4b)`
