A) 1
B) \[{{({{m}_{p}}/{{m}_{e}})}^{1/2}}\]
C) \[{{({{m}_{e}}/{{m}_{p}})}^{1/2}}\]
D) 1836
Correct Answer: B
Solution :
For electron \[s=\frac{eE}{{{m}_{e}}}\times t_{1}^{2}\], For proton \[s=\frac{eE}{{{m}_{p}}}\times t_{2}^{2}\] \ \[\frac{t_{2}^{2}}{t_{1}^{2}}=\frac{{{m}_{p}}}{{{m}_{e}}}\,\Rightarrow \frac{{{t}_{2}}}{{{t}_{1}}}=\sqrt{\frac{{{m}_{p}}}{{{m}_{e}}}}={{\left( \frac{{{m}_{p}}}{{{m}_{e}}} \right)}^{1/2}}\]You need to login to perform this action.
