💡 Solution & Explanation

Sol. Let R be the radius of the circular layer of water. Then, R2d   = m …(1) Pressure at 0 2T A p d   …(2) Thus pressure between the plates is less than the atmospheric pressure and so the plates are pressed together as though attracted towards each other. F, force of attraction = p  area  2 2T F R d   d A T  3 2 2 4 2T m 2Tm 2
