The stopping potential in an experiment ...

The stopping potential in an experiment on photoelectric effect is 2V. What is the maximum kinetic energy of the photoelectrons emitted ?

Text Solution

Verified by Experts

Here `V_(0)=2 V`
`:. K_("max")=eV=3.2 J=1.6x10^(-6) xx2" "[ :' 1 eV=1.6xx10^(-19) J]`
