Water is filled to a height of 2.5 m in a container lying rest on a horizontal surface as shown in the figure. The bottom of the container is square shaped of side sqrt(3) and its top is open. There is a very small hole in the vertical wall of the container near the bottom. A small cap closes the hole. The hole gets opened when pressure near the bottom becomes more than 4 xx 10^(4) pascal a, What minimum acceleration can be given to the container in the positive x -direction so that the cap will come out of the hole?
