Let `T_(1)` be surface tension between solid and air, `T_(2)` be the surface tension between solid and liquid and T be the surface tension between liquid and air. Then in equilibrium, for a drop of liquid on a clean glass plate, the correct relation is (`theta` is angle of contact)

A

` cos theta = T/(T_(1)+T_(2))`

B

` cos theta = T /(T_(1)-T_(2))`

C

` cos theta = (T_(1)+T_(2))/T`

D

` cos theta = (t_(1) - T_(2))/T`
