A partical of mass `1kg` rests on rought contact with a plane inclined at `30^(@)` to the horizontal and is just about to slip, Find the coefficient of friction between the plane and the particle.

Explanation

To find the coefficient of friction between the plane and the particle, we can follow these steps:

### Step 1: Identify the forces acting on the particle
The forces acting on the particle include:
- The weight of the particle (W = mg)
- The normal force (N)
- The frictional force (f)
