of the electric field at the position of the $1\mathrm{.}50C$ charge.

magnitude

N$/$C

direction

@ below the $+x-$axis

$($b$)$ How would the electric field at that point be affected if the charge there were doubled?

The magnitude of the field would be halved.

The field would be unchanged.

The magnitude of the field would double.

The magnitude of the field would quadruple.

Would the magnitude of the electric force be affected?

Yes

No
