The mass of a body is 60 kg on the surface of earth. How much will it weigh on a planet whose mass is 3 times and radius is 2 times that of earth ?

Explanation

To calculate the weight of a body on a different planet, we can use the formula for weight, which is given by:

\[ W = m \cdot g \]

where:
- \( W \) is the weight of the body,
- \( m \) is the mass of the body,
- \( g \) is the acceleration due to gravity on that planet.
