The force exerted on Mars is 0.044 times that exerted on Earth using those figures.

#### Explanation:

The gravitation pull on a body by the sun is given by the equation

Given that the mass of Mars is 0.1 that of the Earth and the distance is 1.5 that of the Earth then the relative force is given by
