The reason an astronaut in an earth satellite feels weightless is that

The reason an astronaut in an earth satellite feels weightless is that

1 : the astronaut is beyond the range of the earth's gravity.

2 : the astronaut is falling.

3 : the astronaut is at a point in space where the effects of the moon's gravity and the earth's gravity cancel.

4 : this is a psychological effect associated with rapid motion.

5 : the astronaut's acceleration is zero

A

The correct option is B.

Explanation:

Any object feels weightless in the earth satellite, since it is in a state if freefall towards the Earth. The satellite is moving in the orbit with extremely high speed, so, both the satellite and the astronaut fall with the same acceleration.
