A) l
B) \[\sqrt{\frac{\pi {{\varepsilon }_{0}}}{G}}\]
C) \[\sqrt{\frac{G}{4\pi {{\varepsilon }_{0}}}}\]
D) \[\sqrt{4\pi {{\varepsilon }_{0}}G}\]
Correct Answer: D
Solution :
They will not experience any force if \[|\overrightarrow{{{F}_{G}}}|\,=\,|\overrightarrow{{{F}_{e}}}|\] Þ\[G\frac{{{m}^{2}}}{{{(16\times {{10}^{-2}})}^{2}}}=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{{{q}^{2}}}{{{(16\times {{10}^{-2}})}^{2}}}\]Þ \[\frac{q}{m}=\sqrt{4\pi {{\varepsilon }_{0}}G}\]You need to login to perform this action.
