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

In the figure shown, the minimum force F to be applied perpendicular to the incline so that the block does not slide is

In the figure shown, the minimum force F to be applied perpendicular to the incline so that the block does not slide is

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?

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?

In the above problem what is the minimum force by which 75 N force should be replaced with so that the block does not move.

The coefficient of static friction between the two blocks shown in figure is mu and the table is smooth. What maximum horizontal forced F can be applied to he block of mass M so that the block move together?

Find the minimum value of force (in N) man should apply so that block can move
