A cylindrical tube, with its base as shown in the figure, is filled with water. It is moving down with a constant acceleration a along a fixed inclined plane with angle = 45 . P1 and P2 are pressures at points 1 and 2, respectively, located at the base of the tube. Let = (P1 P2)/( gd), where is density of water, d is the inner diameter of the tube and g is the acceleration due to gravity. Which of the following statement(s) is(are) correct? 
- A= 0 when a = g/
- B> 0 when a = g/
- Cwhen a = g/2
- Dwhen a = g/2
