Suppose your writing table (or desk) is tilted a little. A book kept on the table starts sliding down. Draw a diagram to show the direction of force of friction acting on the book.

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.

The given figure shows a book lying on a table. The book lies as it is because of gravitational force acting upon it. The direction of the gravitational force acting upon the book is

A block of mass m is kept on a horizontal table. If the static friction coefficient is mu ., find the frictional force acting on the block.

In the following figure an object of mass M is kept on a rough table as seen from above. Forces are applied on it as shown. Find the direction of static friction if the object does not move.

The diagram shows a rough plank resting on a cylinder with one and of the plank on rough ground. Negtect friction between plank and cylinder. Draw digrams to show (a) the force acting on the plank, (b)the force acting on the cylinder.

In Figure an object of mass M = 10 kg is kept on a rough table as seen from above forces are appling on it as shown . Find the direction of static friction if the object does not move (Take mu = 0.4)

Two blocks A and b are placed on a table and joined by a string . The limitaing frition for both blocks is F .The tension in the string is T. the forces of friction acting on the blocks are F_(A) and F_(b) An external horizontal force P=3F//2 acts on A, directed aways from B.
