4. Two parallel glass plates are dipped partly in the liquid of density ‘d’ keeping them vertical. If the distance between the plates is ‘x’, surface tension for liquids is T and angle of contact is θ, then rise of liquid between the plates due to capillary will be (a) T cosθ/xd (b) 2T cosθ/xdg (c) 2T/xdg cosθ … Read More
