Figure shows an `L`-shaped tube tilled with a liquid to a height `H`. What should be the horizontal acceleration a of the tube so that the pressure at the point `A` becomes atmospheric.

Text Solution

Verified by Experts

Applying Pascal's law starting from point `B`, we get
`P_(B)+rhogH=rhoaL=P_(A)`
Since `P_(B)=P_(A)=P_("atm")` therefore `a=g(H/L)`
