If the container filled with liquid gets accelerated horizontally or vertically, pressure in liquids gets changed. In case of horizontally accelerated liquid (ax), the free surface has the slope ax/g. In case of vertically accelerated liquid (ay) for calculation of pressure, effective g is used. A closed box with horizontal base 6 m by 6m and a height 2m is half filled with liquid. It is given constant horizontal acceleration g/2 and vertical downward acceleration g/2 .
A cylindrical vessel filled with water is released on an inclined surface of angle θ as shown in the figure. The friction coefficient of surface with vessel is µ (< tan θ). Then the constant angle made by the surface of water with the incline will be
- tan–1 µ
- θ – tan–1 µ
- θ + tan–1 µ
- cot–1 µ
Answer
(A) tan –1 µ
