NEET Physics Degrees of Freedom MCQ Question
Which of the following combinations correctly describe the degrees of freedom of a molecule in different states of motion?
Three for motion in space, two for motion in a plane, one for motion in a line.
Two for motion in space, three for motion in a plane, one for motion in a line.
One for motion in space, two for motion in a plane, three for motion in a line.
Three for motion in a plane, one for motion in space, two for motion in a line.
Correct Answer
Detailed Explanation
A molecule that is free to move in space requires three coordinates, thus having three degrees of freedom for translation. In a plane, it requires two, and along a line, just one, as stated in the context.
