Final answer:
To calculate the force of gravity at a distance 10 times from the Earth's center, use the equation F = G * (m1 * m2) / r^2 and plug in the given values.
Step-by-step explanation:
The force of gravity on a person is given by the equation:
F = G * (m1 * m2) / r^2
Where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers of mass.
In this case, we are given that the force of gravity on a person at Earth's surface is 750 N. To find the force of gravity at 10 times that distance from the Earth's center, we need to multiply the distance by 10 and then use the equation to calculate the new force of gravity.
Let's assume the mass of the person is 60 kg. Plugging in the given values
