Two boys are holding a horizontal rod of length L and weight W through its two ends. If now one of the boys suddenly leaves the rod, what is the instantaneous reaction force experienced by the other boy ?

Explanation

To solve the problem of the instantaneous reaction force experienced by the remaining boy when one boy suddenly leaves the rod, we can follow these steps:

### Step 1: Understand the Setup
We have a horizontal rod of length \( L \) and weight \( W \) held at both ends by two boys. When one boy suddenly releases the rod, we need to analyze the forces and torques acting on the rod.

**Hint:** Visualize the situation clearly. Draw a diagram showing the rod, the two boys, and the forces acting on the rod.

### Step 2: Identify Forces Acting on the Rod
