SUMMARY

The force of gravity acting on an astronaut at a distance of 10 times the Earth's radius is calculated using the formula F = Gm1m2/r^2. Given that the force of gravity at the Earth's surface is 600N, the force at this distance is determined to be approximately 4.96N. The calculation considers the distance from the center of the Earth, which is 11 times the radius when accounting for the astronaut's position above the surface.

PREREQUISITES
  • Understanding of gravitational force equations, specifically F = Gm1m2/r^2
  • Knowledge of Earth's radius and gravitational force at the surface
  • Familiarity with basic physics concepts related to gravity
  • Ability to perform calculations involving ratios and distances
NEXT STEPS
  • Study the implications of gravitational force variations with distance from a mass
  • Learn about the gravitational constant (G) and its significance in physics
  • Explore the concept of gravitational fields and their mathematical representations
  • Investigate real-world applications of gravitational force calculations in space missions
USEFUL FOR

Students studying physics, educators teaching gravitational concepts, and anyone interested in the calculations related to gravitational forces in astrophysics.

Homework Statement


The force of gravity on an astronaut is 600N at the Earth's surface. what is the force of gravity acting on him at a distance of 10 times the Earth's radius?



Homework Equations


F = Fm1m2/r^2


The Attempt at a Solution


F = Gm1m2/r^2
F = 600/11r^2
F = 4.96N

11r because its measured from the surface of the earth

I think it means at a distance of 10 times R from the centre of the Earth. (not from the surface)
