## Question

A liquid of density ðœŒis compin a rectangular box. The bletely filled ox is accelerating horizontally with acceleration 'a'. What should be the gauge pressure at four points P, Q, R, S ?

### Solution

At point P, P_{P }= 0

At point Q, P_{Q }= P_{P} +ðœŒgh = ðœŒgh

At point R, P_{R} = P_{Q} +ðœŒaL +ðœŒgh +ðœŒaL

At point S , P_{S} = P_{R} – ðœŒgh = ðœŒaL
