Question:

Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it.

Answer:

       friction

Frictional force is the opposing force it acts in opposite direction of the object.

When the book slides on the desk, then the friction acts on the opposite direction of the book. In sliding friction, the interlocking between two surfaces is less than the static friction.
