MHT CET 2026 Physics question
The average translational kinetic energy of a molecule in a gas is E. The kinetic energy of the electron (e) accelerated from rest through potential difference 'V' volt is E. The temperature at which E = E possible is (N=number of molecules, R = gas constant)
Answer: (B)
Solution
Average translational kinetic energy of a gas molecule: , where the Boltzmann constant ( is the number of molecules in a mole). So . The kinetic energy gained by the electron is
