Photons of energy 5 eV are incident on cathode. Electrons reaching the anode have kinetic energies varying from 6 eV to 8 eV.
Choose the correct option.
Text Solution
Verified by ExpertsThe correct answer is:
A
when these electrons are accelerated through 5 V, they will reach the anode with maximum energy 
Current is less than the saturation current because if slowest electron also reaches the plate, it would have 5 eV energy at the anode, but there it is given that the minimum energy is 6 eV.
