the maximum kinetic energy of photoelectron is 2.8eV , what is the value of its stopping potential

Dear Student,

The Stopping Potential of an electron can be calculted from its maximum K.E by the following expression

V0=K.Ee   where e=charge on an electronHere,V0=2.8 eVe=2.8 V


  • 2
the relation between kinetic energy and the stopping potential is eV=KEmax where e is the charge on an electron
