A thin square plate of side 5 cm is suspended vertically from a balance so that lower side just dips into water with side to surface. When the plate is clean (θ = 0 degree ), it appears to weigh 0.044 N. But when the plate is greasy (θ =180 degree ), it appears to weigh 0.03 N. The surface tension of water is
