Let mass be m and area of cross section be A
Consider Fig.1, Equilibrium condition
(P 2 −P 1 )A=mg=>P 2>P 1 −−−−−(1)
Consider Fig.2, Applying Newton law considering acceleration 'a' rightward
(P −P 1 )A=ma=>P 2 >P 1 −−−−−(2)
Moving downward left increases pressure,so point 'B' has maximum pressure.
Moving upward right decreases pressure,so point 'D' has minimum pressure
