Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Earth has atmosphere whereas moon doesn’t have any atmosphere. Reason R: The escape velocity on moon is very small as compared to that on earth. In the light of the above statements, choose the correct answer from the options given below: (1) Both A and R are correct but R is NOT the correct explanation of A (2) A is false but R is true (3) Both A and R are correct and R is the correct explanation of A (4) A is true but R is false

1. (1) Both A and R are correct but R is NOT the correct explanation of A
2. (2) A is false but R is true
3. (3) Both A and R are correct and R is the correct explanation of A
4. (4) A is true but R is false

Correct answer: (3) Both A and R are correct and R is the correct explanation of A

Solution

Assertion A is correct because Earth has a substantial atmosphere while the Moon lacks one. Reason R is also correct, as the Moon's lower escape velocity contributes to its inability to retain an atmosphere, making it a valid explanation for Assertion A.
