The electric field and electric potential at any point because of a point charge kept in air is 20 NC -1 and 10 JC -1 respectively. Compute the magnitude of this charge.
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
