Questions  

A light container having a diatomic gas enclosed with in is moving with velocity v. Mass of the gas is M and number of moles is n. The kinetic energy of gas w.r.t. ground is

 

a
12MV2+32nRT
b
12MV2
c
12MV2+52nRT
d
52nRT

detailed solution

Correct option is C

The kinetic energy of gas w.r.t. centre of mass of the system  K.E. = 52nRTKinetic energy of gas w.r.t. ground = Kinetic energy of centre of mass w.r.t. ground + Kinetic energy of gas w.r.t. centre of mass.K.E. = 12MV2+52nRT
