Question

An astronaut inside a small spaceship orbiting around the earth cannot detect gravity. If the space station orbiting around the earth has a large size, can he hope to detect gravity?

Answer 1

Astronauts inside a small spaceship around the earth orbiting very small negligible constant acceleration or we can say value of acceleration is supposed to be constant inside a small spaceship and then feel weightlessness. If space station orbiting around the earth has larger in size then astronaut only experience acceleration due to gravity on the moon or on the moon.
