The radii of the two columns in \( U \) tube are \( r_{1} \) and \( r_{2}\left(r_{2}r_{1}\right) \) When a liquid of density \( \rho \) (angle
\( \mathrm{P} \) of contact is \( \left.0^{\circ}\right) \) is filled in it the level difference

W of liquid in two arms is ' \( h \) '. The surface tension of liquid.
(1) \( \frac{\rho g h r_{1} r_{2}}{2\left(r_{2}-r_{1}\right)} \)
(2) \( \frac{\operatorname{\rho gh}\left(r_{1}-r_{2}\right)}{2 r_{1} r_{2}} \)
(3) \( \frac{2\left(r_{2}-r_{1}\right)}{\rho g h r_{1} r_{2}} \)
(4) \( \frac{\rho g h}{2\left(r_{2}-r_{1}\right)} \)
