A trolley containing a liquid slides down a smooth inclined plane of angle `alpha` with the horizontal. Find the angle of inclination `theta` of the free surface with the horizontal.

A fluid container is containing a liquid of density rho is accelerating upward with acceleration a along the inclined plane of inclination alpha as shown in the figure. Then the angle of inclination theta of free surface is

A body slides down on a rough inclined surface making an angle of 60^@ with the horizontal. Find its acceleration if mu=0.2 .

A container contains some liquid. The container is given a horizontal acceleration alpha . Find the inclination of the free surface of the liquid made with the horizontal.

Assertion: Static slides down an inclined plane if the angle of friction is more than the angle of the inclined plane with the horizontal.
