A solid weighs 32 gf in air and 28.8 gf in water.
Find R.D. of solid

Explanation

To find the relative density (R.D.) of the solid, we can follow these steps:

### Step 1: Understand the given information
- Weight of the solid in air (W_air) = 32 gf
- Weight of the solid in water (W_water) = 28.8 gf

### Step 2: Calculate the loss of weight in water
The loss of weight when the solid is submerged in water can be calculated as:
