The mass of a negative meson is 208 times the mass of electron. If e/m ratio of α-particle is x unit — Atomic Structure Chemistry Question
Question
The mass of a negative meson is 208 times the mass of electron. If e/m ratio of α-particle is x unit, the e/m ratio of this meson will be
Answer: C
💡 Solution & Explanation
(e/m)_α = e/(2m_p) = e/(2×1836×m_e) = x => e/m_e = 3672x. (e/m)_meson = e/(208×m_e) = 3672x/208 = 17.65x.
