If the container filled with liquid gets accelerated horizontally or vertically, pressure in liquid gets changed. In liquid (`a_(y)`) for calculation of pressure, effective `g` is used. A closed box horizontal base `6 m` by `6 m` and a height `2m` is half filled with liquid. It is given a constant horizontal acceleration `g//2` and vertical downward acceleration `g//2`.
What is the value of vertical acceleration of box for given horizontal acceleration `(g//2)`, so that no part of the bottom of the box is exposed?
A. `(g)/(2)` upward
B. `(g)/(4)` downward
C. `(g)/(4)` upward
D. not possible.
