MHT CET 2022 Physics question
The average translational kinetic energy of 'N' molecules in a gas is ''. The kinetic energy of the electron (e) accelerated from rest through potential difference 'V' volt is ''. The temperature at which possible is (R = gas constant, N = number of molecules)
Answer: (D)
Solution
The average translational kinetic energy of a gas molecule at temperature is , where the Boltzmann constant is (here plays the role of the Avogadro number, as required by the form of the options). An electron accelerated from rest through a potential difference
