To find the weight of a body of mass 60 kg at different locations on Earth (the pole, the equator, and at a latitude of 30 degrees), we can use the formula for weight considering the effect of Earth's rotation.
### Step-by-Step Solution:
1. **Given Data:**
- Mass of the body (m) = 60 kg
- Radius of the Earth (R) = 6371 km = \(6371 \times 10^3\) m
- Acceleration due to gravity (g) = 9.8 m/s²
