Photons with energy of 3 eV hit a metal plate in a photoelectric effect apparatus. The metal plate has a workfunction of 5 eV. Group of answer choices Photoelectrons of 5 eV will be generated. Photoelectrons will not be generated. Photoelectrons with enegies of 2 eV will be generated. Photoelectrons of -2 eV will be generated.

Answer ( slope);

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
