question 38

Multiple Choice

In the photoelectric effect, a photon with an energy of 5.3*10^-19 J strikes an electron in a metal. Of this energy, 3.6 *10^-19 J is the minimum energy required for the electron to escape from the metal. The remaining energy appears as kinetic energy of the photoelectron. What is the velocity of the photoelectron, assuming it was initially at rest?

• A) 3.7*10¹⁴ m/s
• B) 3.7 * 10¹¹ m/s
• C) 1.9 * 10⁶ m/s
• D) 6.1 * 10⁵ m/s
• E) 1.7 * 10^-19 m/s
