A rectangular glass plate of dimensions 5 cm `xx` 4 cm is placed flat on the surface of water. Find the downward force on the plate due to surface tension. Given surface tension of water = 0.073 N `m^(-1)`

Explanation

To find the downward force on the rectangular glass plate due to surface tension, we can follow these steps:

### Step 1: Understand the dimensions of the glass plate
The dimensions of the rectangular glass plate are given as:
- Length (L) = 5 cm
- Width (W) = 4 cm

### Step 2: Calculate the perimeter of the plate
