Assertion : Moon has no atmosphere. Reason : The escape velocity for m

1.	Assertion : Moon has no atmosphere. Reason : The escape velocity for moon is less than that for earth.
Answer» If both assertion and reason are true and reason is the correct explanation of assertion If both assertion and reason are truebut reason is notthe correct explanation of assertion If assertion is true but reason is FALSE If both assertionand reason are false. Solution :(a) The escape velocity for earth is 11.2 km `s^(-1)` . The escape velocity for moon is 2.3 km `s^(-1)`. Gas MOLECULES if formed on the surface of the moon having velocities larger than this will escape the GRAVITATIONAL PULL of the moon.
