Question

A liquid of density ${}^{\prime }{\rho }^{\prime }$ taken in a cylinder vessel of diameter ${}^{\prime }{l}^{\prime }$ upto a height of $\frac{l}{2}$ is kept on a horizontal surface. The acceleration with which the vessel should be moved in horizontal direction so that the level of the liquid at wall ${}^{\prime }A{B}^{\prime }$ raises to $l$ is:-

• A. $g$
• B. $2g$
• C. $3g$
• D. $\frac{g}{2}$

Answer 1

The correct option is A $g$

$\tan {45}^0=\frac{a}{g}$

$\Rightarrow a=g$

Hence,

option $\left(A\right)$ is correct answer.
