Questions  

An open vessel containing liquid is moving with constant acceleration a on a levelled horizontal surface. For this situation mark out the correct statement(s).

a
The maximum pressure is at the leftmost bottom corner.
b
Along a horizontal line within the liquid as we move from left to right the pressure decreases.
c
The pressure at all points on a line making an angle of tan−1⁡ag with horizontal would be same.
d
Along a horizontal line within the liquid as we move from left to right, the pressure remains same.

detailed solution

Correct option is A

Pressure decreases in the direction of acceleration. If we take two points 1 and 2, two points in the horizontal line, than we can write p1−p2=ρal. As the inclination of liquid surface with tan⁡θ=a/g. The equipressure lines will be parallel to this line.
