Solution
The correct option is B5m Let the width of base of container be x.
The free surface of the liquid will get tilted and become perpendicular to the net force (of pseudo force & weight) on the fluid mass.
From the triangle shown in figure ΔABC, tan θ=5x...(1)
For horizontally accelerated fluid, tan θ=ag ⇒tan θ=1010=1...(2)
From Eq.(1) and (2), 5x=1 ∴x=5m
