Vedclass · Answer

$\mathrm{q}=1\, \mu \mathrm{C}=1 	imes 10^{-6} \,\mathrm{C}$

$r=4\, \mathrm{cm}=4 	imes 10^{-2}\, \mathrm{m}$

$ 	ext { Potential } V =\frac{\mathrm{k} q}{\mathrm{r}} $

$=\frac{9 	imes 10^{9} 	imes 10^{-6}}{4 	imes 10^{-2}} $

$=2.25 	imes 10^{5}\, \mathrm{V} $

Induced electric field $\mathrm{E}=-\frac{\mathrm{kq}}{\mathrm{r}^{2}}$

$=\frac{9 	imes 10^{9} 	imes 1 	imes 10^{-6}}{16 	imes 10^{-4}}=-5.625\, 	imes 10^{6}\, \mathrm{V} / \mathrm{m}$
