The answer for this exercise is the last option, which is: [tex] -2.0eV [/tex]
The explanation is shown below:
1. The graph shows the Photoelectric effect, which is defined as the ejection of electrons from a solid, this is caused by the incident of ligth. The maximum kinetic energy depends of the frequency of this ligth.
2. You must find the [tex] y-intercept [/tex] the graph shown in the figure attached to solve the exercise:
[tex] y-intercept=-2.0 eV [/tex]
