In physical chemistry, the mean free path is the average distance between the atoms during collision. Its formula is
where d is the diameter of the Nitrogen atom (d = 310 x 10^-7 m), Na is Avogadro's number (Na=6.022 x 10^23), R is the gas constant (8.314 J/mol-K), T is the absolute temperature (T= 20 + 273 = 293 K). Substituting the values,
P = 6.32 x 10^-13 Pascals

The Electric field is E=23400 V/m.
What is electric potential ?
The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential). More specifically, it is the energy per unit charge for a test charge that is negligibly disruptive to the field under discussion.
The electric field of a spherical conductor is given by:
Here 'E' is the electric field and 'Q' is the electric charge.
therefore putting the values we get,
E=23400 V/m
