$1\mathrm{.}0$p $5$a Please select all the statements that are true:

If $Q_3$ is released from rest, it will initially accelerate to the right.

The electric potential at the origin equals $\frac{Q_3}{4{}_{0}d}.$

$($Recall that $($:$k=\frac{1}{4{}_0}\}$

The electric field at the origin points solely in the positive $y$ direction.

The electric potential at any point along the $y-$axis is positive.

The external work done to bring these charges to this configuration $($from infinity$)$ was positive.

The work required to move $Q_3$ from its present position to the origin is zero.

The force on $Q_3$ due to the other two charges is zero.
