A block of weight `100N` lying on a horizontal surface just beging to when a horizontal to move when a horinzontal force of `25 N` acts on it Determine the coefficent of static friction

Explanation

To determine the coefficient of static friction (μ) for the block, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Forces Acting on the Block**:
- The weight of the block (W) is given as 100 N, acting vertically downward.
- The normal force (N) acting on the block is equal to its weight since the block is on a horizontal surface, so N = W = 100 N.
- A horizontal force (F) of 25 N is applied to the block, which is just enough to overcome static friction and initiate movement.
