A) \[8e\]
B) \[6e\]
C) \[3e\]
D) \[2e\]
Correct Answer: C
Solution :
\[E=\frac{V}{d}=\frac{800}{2\times {{10}^{-2}}}V\text{/}m=4\times {{10}^{4}}V\text{/}m\] again, \[qE=mg\] \[q=\frac{mg}{E}=\frac{1.96\times {{10}^{-15}}\times 9.8}{4\times {{10}^{4}}}e\] \[=3e\]You need to login to perform this action.
