Question

How can maximum kinetic energy be written in terms of stopping potential \[V_0\]?

Options

• \[K_{\max}=eV_0\]

• \[K_{\max}=V_0/e\]

• \[K_{\max}=e/V_0\]

• \[K_{\max}=e+V_0\]

Answer 1

The maximum kinetic energy of photoelectrons can be written as \[K_{\max}=eV_0\]. This relates maximum kinetic energy to the stopping potential.
