MHT CET 2026 Physics question
The average transnational kinetic energy of a molecule 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 (mass of molecule and electron is same) (N=number of molecules, V = Velocity, R=gas constant)
Answer: (A)
Solution
Reading as the accelerating potential difference (in volt, as in the stem), the average translational kinetic energy of one molecule is with ( is the Avogadro number of molecules per mole). The electron
