$$2q\ell \widehat j$$
$$\left( {q\ell } \right){{\widehat i + \widehat j} \over {\sqrt 2 }}$$
$$\sqrt 3 \,q\ell {{\widehat j - \widehat i} \over {\sqrt 2 }}$$
$$ - \sqrt 3 \,q\ell \widehat j$$
Explanation

$$\left| {{P_1}} \right| = $$ q(d)
$$\left| {{P_2}} \right| = $$ qd
|Resultant| $$=$$ 2 P cos30o
2 qd$$\left( {{{\sqrt 3 } \over 2}} \right)$$ = $$\sqrt 3 $$ qd
