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

Astronaut inside a small spaceship experience a very small negligible constant acceleration and hence astronaut feel weight less ness. If the space station has too much large mass and size then he can only experience acceleration due to gravity in the proximity of moon or on the moon.

A boy is standing on a platform which is free to rotate about its axis. The boy holds an open umbrella in his hand. The axis of the umbrella coincides with that of the platform. The moment of inertia of ''the platform plus the boy system'' is 3.0 × 10-3kg-m2 and that of the umbrella is 2.0 × 103kg-m2. The boy starts spinning the umbrella about the axis at an angular speed of 2.0rev/s with respect to himself. Find the angular velocity imparted to the platform.
