Zarra 0,5c tezlik bilan harakatlanayotgandagi massasi m/√ 3 ga teng. a) Zarraning tinchlikdagi massasini…

a) $\frac{m_0}{\sqrt{1-0{,}25}}=\frac{2m_0}{\sqrt 3}=\frac{m}{\sqrt 3}$, demak $m_0=\frac{m}{2}$. b) 0,6$c$ da $\gamma=\frac{1}{\sqrt{1-0{,}36}}=1{,}25$. $E_k=(\gamma-1)m_0c^2=0{,}25\cdot\frac{m}{2}c^2=\frac{mc^2}{8}$.
