Two point charges, $-1\mathrm{.}5\backslash$mu C and $3\mathrm{.}51\backslash$mu C$,$ are placed at x $=0$ cm and x $=11\mathrm{.}6$ cm$,$ respectively. Consider the x$-$axis directed to the right.

$1\mathrm{.}0$p

a$)$ At what point along the x axis is the electric field zero?

$($Please answer in SI unit and multiply your answer by $10^1)$ b$)$ At what points along the x$-$axis is the electric potential zero $($leftmost first$)?$ Let V $=0$ at r $=\backslash$infty $.$ Please enter the smaller answer here c$)$ At what points along the x$-$axis is the electric potential zero $($leftmost first$)?$ Let V $=0$ at r $=\backslash$infty $.$ Please enter the larger answer here
