A car containing a beaker of water is moving horizontally on a level road. Consider two points, A & B, inside the water such that they are on the same horizontal level and are separated by a distance L. Which of the following options is correct regarding the pressure differences between those two points?

If car is moving with constant acceleration a, PA PB = (g+a)L

If car is accelerating with acceleration a, PA PB = gL

If car is accelerating with acceleration a, PA PB = 0

If car is moving with constant velocity, PA PB = 0

If car is moving with constant acceleration a, PA PB = (g+a)L
