A body starts rolling down an inclined plane , the top half is rough . Find the ratio of the force of friction and weight of the body if the body is brought to rest just when it reaches the bottom , the angle of the plane being `30^(@)` .

A body starts sliding down an inclined plane of inclination 30°, the top (1/4)^(th) of inclined plane is smooth and lower (3/4)^(th) is rough. The ratio of force of friction and weight of body, if the body is brought to rest, just when it reaches the bottom is

A body starts sliding down an inclined plane of inclination 30^(@) ,the top ((1)/(4))^( th ) of inclined plane is smooth and lower ((3)/(4))^(th) is rough.The ratio of force of friction and weight of body,if the body is brought to rest,just when it reaches the bottom is

A body slides down an inclined plane having friction. Indicate the directions of the frictional force and the reaction of the plane on the body.

A body starts rolling down an inclined plane of length L and height h. This body reaches the bottom of the plane in time t. The relation between L and t is?

A body starts rolling down an inclined plane of length L and height h. This body reaches the bottom of the plane in time t. The relation between L and t is?

When a body is lying on a rough inclined plane and does not move, the force of friction

If the body starts from rest from the top of the rough inclined plane of length 1, time taken to reach the bottom of the plane is

When a body rolls without sliding up an inclined plane the frictional force is :
