A body weighs `54 kg f` on the surface of Earth. How much will it weigh on the surface of mers whose mass is `1//9` and the redius is `1//2` of that of earth?

Explanation

To find the weight of a body on the surface of Mars, we can use the relationship between weight, mass, and gravitational acceleration. The weight of a body is given by the formula:

\[ W = mg \]

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