Atomic Structure Question 26

Question: The specific charge of proton is $ 9.6\times 10^{6}C,k{g^{-1}} $ then for an a-particle it will be [MH CET 1999]

Options:

A) $ 38.4\times 10^{7}C,k{g^{-1}} $

B) $ 19.2\times 10^{7}C,k{g^{-1}} $

C) $ 2.4\times 10^{7}C,k{g^{-1}} $

D) $ 4.8\times 10^{7}C,k{g^{-1}} $

Show Answer

Answer:

Correct Answer: D

Solution:

$ {{( \frac{q}{m} )} _{\alpha }}=\frac{1}{2}{{( \frac{q}{m} )} _{p}}=\frac{1}{2}\times 9.6\times 10^{7}=4.8\times 10^{7}C,k{g^{-1}} $
