Drop in pressure due to formation of meniscus in first column=\dfrac{2T}{r_1}
Drop in pressure due to formation of meniscus in first column=\dfrac{2T}{r_2}

Hence the heights of liquids in the two columns differ to balance the excess drop in pressure in one of hte arms.

Hence\rho gh=2T(\dfrac{1}{r_1}-\dfrac{1}{r_2})
\implies T=\dfrac{\rho ghr_1r_2}{2(r_2-r_1)}
