The photoelectric current of voltage in a certain experiment is 1.5 ~V . What is the maximum kinetic energy of photoelectrons emitted?

Options

  1. A24 10⁻¹⁹ ~J
  2. B-24 10⁻¹⁹ ~J
  3. C2.4 10⁻¹⁹ ~J
  4. D2.04 10⁻¹⁹ ~J

Correct answer

C. 2.4 10⁻¹⁹ ~J

Step-by-step solution

Given, V₀=15 ~V Maximum kinetic energy of emitted photoelectron, aligned K_ &=e V₀ &=1.6 10⁻¹⁹ 1.5=2.4 10⁻¹⁹ ~J aligned
