Question and Answer

The law of equipartition of energy is applicable to the system whose constituents are :
(A) in random motion
(B) in orderly motion
(C) at rest
(D) moving with constant speed

Answer

Answer: A
The original idea of equipartition is to assign a average kinetic energy to each degree of freedom if we take transnational case only. So if there would be ordered motion instead of random motion then there is no need of equilibrium theorem as it would be useless to take about averages as they all are in ordered motion.
Hence, the answer is in random motion.
