Question 11.C-A.67: Electrons emitted from the surface of a cathode have suffici...

Pearson IIT Foundation Series Physics Class 10

Electrons emitted from the surface of a cathode have sufficient kinetic energy to reach the anode even if the anode is at a negative potential. In a vacuum diode, no current flows when the anode potential is less than –5 V. Find the maximum kinetic energy of the electrons in electron volt, emitted from the cathode surface.
