Question

Statement I : A person sitting in an artificial satellite revolving around the earth feels weightless.
Statement II : There is no gravitational force on the satellite.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I
• C. If statement I is true but statement II is false
• D. If both statement I and statement II are false

Answer 1

Answer: (C)

A person feels his weight only when the surface on which he is standing exerts a reactionary force on him Because the acceleration of the person and that of the satellite revolving round the earth are equal $(=g)$, hence acceleration of the person with respect to the satellite is zero.
Therefore person feels weightless on satellite, although the gravitational force is acting on a satellite.
