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).

Options

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 a of `tan^(-1)(a/g)` with horizontal would be same.
D. Along a horizontal line within the liquid as we more from left to right, the pressure remains same.

Answer

A, B, C

Explanation

Pressure decreases in the directionof acceleration. If we take two points `1` and `2`, two points in the horizontal line, then we can write `p_(1)-p_(2)=rhoal`.
As the inclination of liquid surface with `tantheta=a/g`. The equipressure lines will be paralel to this line.
