Once the space shuttle is in orbit at a radius R from earths's centre what force does the seat exert on the astronout?
Correct answer: B. Zero newton
- A. mg
- B. Zero newton
- C. m/g
- D. mg/R2
Explanation
Zero. The force of gravity is counterbalanced by the force of angular acceleration.That's how it stays in orbit.Have you ever seen any commentary on astronauts in spaceships? They are floating in a spaceship too, with no force.
