Determine the magnitude of the gravitational force mars would exert on man if he was on the surface of mars. the mass of the man is 68.0 kg . the mass of the mars is 6.42×1023kg and its radius is 3396 km

252.6 N

Explanation:

To calculate the force between two bodies, we employ Newton's Law of gravitation which mathematically, tells us that the force of gravity between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance of separation between their centers.
