Answer: Option A Many have the misconception that as the astronaut and camera are floating and weightless, there is no gravitational force acting on them. Actually both are inside the gravitational field of the Earth, and there is gravitational field strength, hence there is gravitational force acting on them towards the Earth. But as together with the station, they are all ‘free falling’, hence no normal contact force on the astronaut and camera, hence give the feeling of we

Answer: Option A W = mg, where g is the gravitational field strength. g = W/m, hence g is the gravitational force (pull) acting per unit...
