3.597 N/kg

#### Explanation:

According to Newton's law of universal gravitation, the force of gravity is equal to the gravitational constant (G) multiplied by both masses, all over the square of the distance between them:

Since we want to work out the force per kilogram on mars, we can divide the above equation by

Plugging in Mars' mass and its radius, as well as the gravitational constant (
