What should be the minimum force P to be applied to the string so that block of mass m just begins to move up the frictionless plane?

An inclined plane is inclined at an angle theta with the horizontal. A body of mass m rests on it, if the coefficient of friction is mu , then the minimum force that has to be applied to the inclined plane to make the body just move up the inclined plane is

What is the minimum value of F needed so that block begins to move upward on frictionless incline plane as shown

What is the minimum value of F needed so that block begins to move upward on frictionless incline plane as shown

Find out the minimum force that must be applied on the block vertically downwards so that the block doesn’t move.

What force should be applied on the wedge so that block over it does not move? (All surfaces are smooth)

What force should be applied on the wedge so that block over it does not move? (All surfaces are smooth)

Figure shown a block of mass m placed on a smooth wedge of mass M. Calculate the minimum value of M' and tension in the string, so that the block of mass m will move vertically downwards with acceleration 10ms^(-2)

A block of mas M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is theta the block just begins to slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane ?
