A cubical contaienr of side length L is filled completely with water. The container is closed. It is acclerated horizontally with acceleration a. Density of water is `rho`.

(a) Assuming pressure at point 1 (upper right corner) to be zero, find pressure at point 2 (upper left corner).
(b) Pressure at point 4, at a distance h vertically below point 2 , is same as pressure at lower right corner 3. find h.

Answer

(a) `rhoaL`
(b) `h=L(1-(a)/(g))`
