To find the decrease in weight of a body of mass 800 kg when taken into a mine of depth 1500 m, we can follow these steps:
### Step 1: Write down the given data
- Mass of the body (M) = 800 kg
- Depth of the mine (D) = 1500 m
- Radius of the Earth (R) = 6371 km = 6371 × 10^3 m
### Step 2: Calculate the weight of the body at the surface of the Earth
