NEET Physics Degrees of Freedom Assertion Reason Question
Assertion (A): A molecule constrained to move in a plane has two degrees of freedom.
Reason (R): Motion in different spatial dimensions requires different numbers of coordinates.
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.
Correct Answer
Detailed Explanation
According to the NCERT content, a molecule constrained to a plane requires two coordinates to specify its location, which corresponds to two degrees of freedom. The reason explains the assertion by addressing the relationship between spatial dimensions and degrees of freedom.
