The average translational kinetic energy of $N$ molecules in a gas is $E_1$. The kinetic energy of the electron $(e)$ accelerated from rest through potential difference $V$ volt is $E_2$. The temperature at which $E_1=E_2$ is possible is ( $R=$ gas constant,$N=$ number of molecules).
- A$\frac{3 V N e}{2 R}$
- B$\frac{V N e}{2 R}$
- C$\frac{V N e}{3 R}$
- D$\frac{2 V N e}{3 R}$
