When the spacecraft is located at exactly the halfway point between Earth and Mars, how does the strength of the gravitational force on the probe by Earth compare with the strength of the gravitational force on the probe by Mars?

Answer is give below

Explanation:

when any object or spacecraft is located exactly between Earth and Mars.

than Earth gravitational force will be exerted on spacecraft more than the Mars gravitational force.

as we know that gravity on the Mars is less than the gravity on the Earth

so spacecraft will move very slowly toward the Earth.

gravity force on Earth =  9.807 m/s²

gravity force on Mars =   3.711 m/s²
