Question 24

A block of mass 25 kg, is at rest on a rough horizontal floor. The coefficient of friction between the block and the floor is 0.4. A force of F F\,F N is pulling the block at an angle of 20∘ 20^\circ\,20∘ to the horizontal. The block is on the point of sliding.

Diagram for Question 3: A block of mass 25 kg is on a rough horizontal floor. A force F is applied to the block at an angle of 20 degrees to the horizontal.
