NEET Physics Degrees of Freedom Assertion Reason Question
Assertion (A): A molecule free to move in space has three degrees of freedom. | Reason (R): A molecule constrained to move in a plane has two degrees of freedom.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
Both statements are true. A molecule free to move in space does have three degrees of freedom due to translational motion, and a molecule constrained to a plane has two degrees of freedom. However, the reason doesn't explain the assertion directly.
