A person sitting in a chair in a satellite feels weightless because the normal force is zero
Explanation:
- Different bodies exert different gravitational force on other bodies depending upon their mass. The satellite revolves around the earth in its own orbit.
- Also, the gravitational force exerted by the earth on the satellite is balanced by the centripetal force due to which the satellite revolves around the earth.
- Hence, the person sitting in the chair inside the satellite will experience no gravitational force from the earth.
