Question

As we are travelling to Mars, let’s try to get an idea of whether the largest gravitational force we will experience will be due to the Earth or the Sun. Calculate the distance from the center of the Earth where the gravitational force from the Earth and from the Sun are equal (for simplicity, you may consider this distance along the straight line between the Earth and the Sun). Then discuss briefly whether the result of your calculation implies that the larger gravitational force on our journey to Mars will be from the Earth or the Sun.
