Solution

The correct option is C Less than 5 N
Here, the maximum value of static friction between the block and the table is 5 N. Once the block start sliding, kinetic friction will come into play. As kinetic friction is less than static friction, its value will be less than 5 N.

A block needs 50 N of force to move it and you are applying 5 N of force on that block in the horizontal direction. So how much frictional force will the surface be applying on the block?

A block, kept on ground, requires 10 N of horizontal force to just start moving. If we apply a force of 5 N on the block in horizontal direction, what will be the magnitude of frictional force acting on it?

Q. A wooden block kept on concrete was initially at rest. When a force of 20 N acts on it, the block starts to move in the direction of force. Which of the following is correct for the friction on the block when it is moving?
