The radii of two columns in a U-tube are r_{1} and r_{2}. When a liquid of density \rho (angle of contact =0^{\circ}) is filled in if, the level difference of liquid in two arms is h. The surface tension of liquid is

Correct Answer is : r1r2ρgh2(r2−r1)

{(r_{1}-r_{2}) \rho g h}/{2 r_{1} r_{2}}

{r_{1} r_{2} \rho g h}/{(r_{1}-r_{2})}

{r_{1} r_{2} \rho g h}/{2(r_{2}-r_{1})}

{r_{1} r_{2}(\rho g h)}/{2(r_{1}-r_{2})}
