JEE Main 25 February 2021, Shift 2, Physics Q6

Question 6 of 90 in this shift, Physics question 6 of 30, Section A.

Given below are two statements : Statement I : In a diatomic molecule, the rotational energy at a given temperature obeys Maxwell’s distribution. Statement II : In a diatomic molecule, the rotational energy at a given temperature equals the translational kinetic energy for each molecule. In the light of the above statements, choose the correct answer from the options given below :
  1. (1)Both Statement I and Statement II are true.
  2. (2)Both Statement I and Statement II are false.
  3. (3)Statement I is true but Statement II is false.Official answer
