Question

Photoelectric current in an experimental study of photoelectric effect is made zero by making anode negative with respect to cathode. If stopping potential is V0, then (A) kinetic energy of emitted photoelectron is K=e V0 (B) for every emitted photoelectron kinetic energy K ≥ eV (C) maximum kinetic energy of emitted electrons K max =e V0  (D) sum of kinetic energies of emitted photoelectrons is Sigma K=e V0

Photoelectric current is zero when the stopping potential is sufficient to repel even the most energetic photoelectrons, with the maximum kinetic energy (K max ), so that K max =e V0

Q. Photoelectric current in an experimental study of photoelectric effect is made zero by making anode negative with respect to cathode. If stopping potential is $V_{0}$ , then

kinetic energy of emitted photoelectron is $K = e V_{0}$

for every emitted photoelectron kinetic energy $K \geq e V$

maximum kinetic energy of emitted electrons $K_{m a x} = e V_{0}$

sum of kinetic energies of emitted photoelectrons is $Σ K = e V_{0}$

Photoelectric current is zero when the stopping potential is sufficient to repel even the most energetic photoelectrons, with the maximum kinetic energy $(K_{m a x})$ , so that $K_{m a x} = e V_{0}$

Q. Photoelectric current in an experimental study of photoelectric effect is made zero by making anode negative with respect to cathode. If stopping potential is V0​, then

kinetic energy of emitted photoelectron is K=eV0​

for every emitted photoelectron kinetic energy K≥eV

maximum kinetic energy of emitted electrons Kmax​=eV0​

sum of kinetic energies of emitted photoelectrons is ΣK=eV0​
