Gravity The gravitational force F exerted by the earth on an object having a mass of 100 kg is given by the equation:
where d is the distance (in km) of the object from the center of the earth, and the force F is measured in newtons (N). For what distances will the gravitational force exerted by the earth on this object be between 0.004 N and 0.1 N?
