A) \[\frac{E{{q}^{2}}m}{2{{t}^{2}}}\]
B) \[\frac{2{{E}^{2}}{{t}^{2}}}{mq}\]
C) \[\frac{{{E}^{2}}{{q}^{2}}{{t}^{2}}}{2m}\]
D) \[\frac{Eqm}{t}\]
Correct Answer: C
Solution :
\[{{E}_{k}}=\frac{1}{2}m{{v}^{2}}\,=\,\,\frac{1}{2}m\,{{\left( \frac{qE}{m}t \right)}^{2}}\,\,=\,\,\frac{{{q}^{2}}{{E}^{2}}{{t}^{2}}}{2m}\] \[v=at=\frac{qE}{m}t\]You need to login to perform this action.
