    A closed cubical box is completely filled with water and is accelerated horizontally towards right with an acceleration α. The resultant normal force by the water on the top of the box
    (a) passes through the centre of the top
    (b) passes through a point to the right of the centre
    (c) passes through a point to the left of the centre
    (d) becomes zeros
    digAnsr:   c
    Ans : (c) passes through a point to the left of the centre
    When the box is accelerated towards right, the water in the box experiences a pseudo force (ma) towards left, where m is the mass of water. So, the resultant normal force by the water on the top of the box passes through a point to the left of the centre.
