CAIE A-Level Mathematics AS 4.1.1 Forces Questions

Practise representing forces on particles and blocks with clear free-body diagrams.

Exam points

identify and label forces acting on a particle or block
draw complete free-body diagrams for mechanics problems
distinguish applied forces and their directions in equilibrium setups

[Maximum number: 1]

A particle of mass 12 kg is stationary on a rough plane inclined at an angle of $25^{\circ}$ to the horizontal. A force of magnitude $P \mathrm{~N}$ acting parallel to a line of greatest slope of the plane is used to prevent the particle sliding down the plane. The coefficient of friction between the particle and the plane is 0.35 .

Draw a sketch showing the forces acting on the particle.

The force diagram should show the weight vertically downward, the normal reaction perpendicular to the plane, the force P parallel to the line of greatest slope, and the friction force F along the plane opposing the tendency to slide. The angle of inclination is $25^\circ$ .
