$nC$ is located at $(a,0),$ where $a=1\mathrm{.}5m.$ The point $P$ has coordinates $(a,b),$ where $b=0\mathrm{.}55m.$A tnird charge $q_3=19nC$ will be placed later.

$33\%$ Part $($a$)$ Find the electric potential $V_P$ at point $P,$ in volts. Assume the potential is zero at infini $V_P=98\mathrm{.}80$

$$ Correct!

$33\%$ Part $($b$)$ How much work $W,$ in joules, would you have to do to bring the third charge, $q_3,$ fror

$W=1828**{10}^{-9}$

$W=1\mathrm{.}828{10}^{-6}$

$$ Correct!

$33\%$ Part $($c$)$ What is the total potential energy $U,$ in joules, of the final configuration of three char

$U=$
