A vessel containing water is given a constant acceleration 'a? towards the right along a straight horizontal path. Which of the following diagrams represents the surface of the liquid?

A)

B)

C)

D) None of these

Correct Answer: C

Solution :

[c] Let us consider a small dotted segment of thickness dx for observation. Since, this segment is accelerated towards right, a net force is acting in this segment towards right from the liquid towards the left of ABCD. According to Newton's third law, the segment ABCD will also apply a force on the previous section creating a pressure on it which makes the liquid rise.?
