Question $3$

In the figure above, charge A is $-3\mathrm{.}55nC,$ charge $B$ is $3\mathrm{.}55nC,$ and charge $C$ is $-1\mathrm{.}78nC.$ If $x=2\mathrm{.}50cm$ and $y=1\mathrm{.}50cm,$ what is the electric

field at the dot?

$1\mathrm{.}71{10}^5\frac{N}{C},86\mathrm{.}9$ counter$-$clockwise from the positive $x-$axis

$1\mathrm{.}23{10}^5\frac{N}{C},23\mathrm{.}5$ clockwise from the positive $x-$axis

$1\mathrm{.}23{10}^5\frac{N}{C},86\mathrm{.}9$ clockwise from the negative $x-$axis

$1\mathrm{.}71{10}^5\frac{N}{C},23\mathrm{.}5$ clockwise from the negative $x-$axis
