Question $1$

A point charge located at the origin generates an electric field that has the value vec$(E)=(640.\frac{N}{C})hat(i)+(590.\frac{N}{C})hat(j)$ at the point $(x,y)=(1\mathrm{.}00cm,5\mathrm{.}20cm).$ What is

the value of the charge?

$0\mathrm{.}271nC$

$5\mathrm{.}13nC$

$0\mathrm{.}184nC$

$0\mathrm{.}200nC$
