A block lying on an inclined plane has a weigh of `50 N` .It just beings to side down when inclination of plane with the horizontal is `30^(@)` find the coefficient of static plane friction .

Explanation

To find the coefficient of static friction (μ) for a block lying on an inclined plane, we can follow these steps:

### Step 1: Identify the forces acting on the block
The block has a weight (W) of 50 N acting vertically downward. When the block is on an inclined plane at an angle θ (30 degrees), we can resolve the weight into two components:
- The component parallel to the incline: \( W_{\parallel} = W \sin(\theta) \)
- The component perpendicular to the incline: \( W_{\perpendicular} = W \cos(\theta) \)

### Step 2: Calculate the components of the weight
