Answer to Question #174950 in Mechanics | Relativity for Obada

Question

Find the greatest angle through which a nonrelativistic alpha partiClec can be deflected by striking a stationary proton.[14°]

Answer 1

Answer

the greatest angle through which a nonrelativistic alpha partiClec can be deflected by striking a stationary proton is given by

$tan\theta_1=\frac{sin\theta }{cos\theta +m_{\alpha}/m_p}\\=\frac{sin14° }{cos14° +4m_p/m_p}\\=\frac{0.24}{4.97}\\=0.048$

$\theta_1=2.75°$
