Vedclass · Answer

(C) The mass of an alpha particle $(m_{\alpha} \approx 6.64 	imes 10^{-27} \ kg)$ is approximately $7300$ times larger than the mass of an electron $(m_e \approx 9.11 	imes 10^{-31} \ kg)$.According to the laws of conservation of momentum and energy,when a very heavy particle collides with a very light particle,the energy transferred to the light particle is negligible.Therefore,the alpha particle loses only a very small fraction of its kinetic energy during the collision with an electron.Thus,the correct option is $C$.
