[URGENT! Stopping Potential~~~~~~~#######~~~~~~~~~~~~~~~~
max Kinetic_energy= e*Vs=hfwork_function
Vs is the stopping potential
The attempt at a solution
I am wondering, does this stopping potential refers the voltage difference of
V_Emitter (where the line shines on)  V_collector(where the electron travels to), and thus, the stopping potential is usually positive?
Also, for that equation max kinetic_energy= e*Vs, 'e' is just the charge= +ve 1.602*10^19?
so that the max kinetic energy in this case, (+5 V)*(+ 1.602*10^19)= +ve number?
