Physics Gravitation JEE Main

Assertion: An astronaut in an orbiting space station above the Earth experiences weightlessness. Reason: An object moving around the Earth under the influence of Earth's gravitational force is in a state of 'free-fall'.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
