SUMMARY
An astronaut weighing 99.3 N on the surface of the Moon experiences a reduced gravitational force when orbiting at an altitude equal to the Moon's radius. The gravitational force can be calculated using the formula F = G(m1*m2)/r², where G is the gravitational constant, m1 is the mass of the Moon, m2 is the mass of the astronaut, and r is the distance from the center of the Moon to the astronaut. At this altitude, the gravitational force exerted on the astronaut is approximately 24.8 N.
