Two charges, $Q_1=+16\mathrm{.}0C$ and $Q_2=-8\mathrm{.}00C$ are separated by $12\mathrm{.}0cm$ on the $x-$axis as shown. The charges

produce an electric field in the surrounding region. Consider only the electric field along the $x-$axis.

$($x and y show the coordinate axis$)$

At any point between the charges, the net electric field points to the right.

a$)$ True

b$)$ False

At any point to the left of $Q_1,$ the net electric field points to the left.

a$)$ True

b$)$ False

What is the magnitude of the net electric field at the point midway between the charges?

a$)20\mathrm{.}0{10}^6\frac{N}{C}$

b$)40\mathrm{.}0{10}^6\frac{N}{C}$

c$)60\mathrm{.}0{10}^6\frac{N}{C}$

d$)80\mathrm{.}0{10}^6\frac{N}{C}$
