A photon and a nonrelativistic electron have the exact same kinetic energy \(K\). The electron has mass \(m_e\), and the speed of light in a vacuum is \(c\). Which of the following expressions represents the ratio \(\dfrac{p_{\text{photon}}}{p_{\text{electron}}}\) of the magnitude of the photon's momentum to the magnitude of the electron's momentum?
