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

Text Solution

Verified by Experts

Inside a small spaceship orbitting around the earth, the value of acceleration due to gravity g, can be considered as constant and hence astronaut feels weightlessness.
In the space station orbitting around the earth has a large size, such that variation in `g` matters in the case astronaut inside the speceship will experience gravitational force and hence can detect gravity e.g., On the moon, due to larger size gravity can be detected.

Answer the following : An astronaut inside a small space ship 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 the following: (a) You can shield a charge from electrical forces by putting it inside a hollow conductor. Can you shield a body from the gravitational influence of nearby matter by putting it inside a hollow sphere or by some other means? (b) 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? (c) If you compare the gravitational force on the Earth due to the Sun to that due to the Moon, you would find that the Sun’s pull is greater than the Moon’s pull. (You can check this yourself using the data available in the succeeding exercises). However, the tidal effect of the Moon’s pull is greater than the tidal effect of Sun. Why?
