NEETPhysicsGravitation
Assertion A An astronaut inside a massive spaceship orbiting around the earth will experience a finite but small gravitational force. Reason R The centripetal force necessary to keep the spaceship in orbit around the earth is provided by the gravitational force between the earth and the spaceship.
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true and (R) is not the correct explanation of (A)
- C(A) is true but (R) is not true
- D(A) is not true but (R) is true
Correct answer
D. (A) is not true but (R) is true
Step-by-step solution
Astronaut would not experience any gravitational force as it is balanced by centrifugal force. So, A is false and R is true.
