A $10-cm-$long thin glass rod uniformly charged to $14\mathrm{.}0nC$ and a $10-$cm$-$long thin plastic rod uniformly

charged to $-14\mathrm{.}0nC$ are placed side by side, $3\mathrm{.}50cm$ apart. What are the electric field strengths $E_1$ to

$E_3$ at distances $1\mathrm{.}0cm,2\mathrm{.}0cm,$ and $3\mathrm{.}0cm,$ from the glass rod along the line connecting the midpoints

Specify the electric field strength E$1.$

Specify the electric field strength E$2.$

Specify the electric field strength E$3.$
