Answer to Question #1066 in Mechanics | Relativity for Micah

Question

A 100 kg astronaut in space is at the midpoint between two stars of equal mass. If all other objects are infinitely far away, what is the mass of the astronaut and the force of gravity on the astronaut?

Answer 1

As the distances from the astronaut to each star are equal, gravity forces are equal too and directed oppositely, so the net force is null: F-F = 0.
