Question

Reason of weightlessness in a satellite is

• A. zero gravity
• B. zero reaction force due to the satellite surface
• C. the centre of mass
• D. can’t be said

Answer 1

The correct option is B

zero reaction force due to the satellite surface

Due to gravity, all bodies are attracted towards the Earth’s centre and weight is due to gravity, it is the value of natural reaction force at any contact force. Since the satellite is in a state of free fall therefore the normal reaction at any surface on the satellite is zero.
