A tightly fitted piston can slide along the inner wall of a long cylindrical pipe. With the piston at the lower end of the pipe, the lower end of the pipe is dipped into a large tank, filled with water. Now the piston is pulled up with the help of the rod attached to it. water rises in the pipe along with the piston. Why? To what maximum height water can be raised in the pipe using this method? What will be the answer to your question if water is replaced with mercury? Atmosphere pressure is `P_(\"atm\")=1.01xx10^(5)Pa`.
