A block is placed on an inclined plane whose angle `theta` can be varied as shown. Given `mu_(0)=3//4` and `mu_(k)=1//2`. The angle at which block starts moving and minimum acceleration of the block once it starts moving is

The angle of inclination is slowly increased. Find out the angle at which the block starts moving.

An inclined plane is inclined at an angle theta when the block placed on it is just at the point of moving down the plane. What can be minimum acceleration with which the block can be moved up the inclined plane?

A block is placed on a smooth inclined plane at an angle 'theta' to the horizontal. The acceleration must the plane be moved horizontally so that the block to fall freely is

A block is lying on an inclined plane which makes an angle of 60^@ with the horizontal. If coefficient of friction between the block and the plane is 0.25 and g = 10 ms^(-2) , the acceleration of block when it is moves along the plane will be

A block of mass m slides down an inclined plane which makes an angle theta with the horizontal. The coefficient of friction between the block and the plane is mu . The force exerted by the block on the plane is
