3. Two charges are placed as shown in Figure 3. The magnitude of \( \mathrm{q} 1 \) and \( \mathrm{q} 2 \) is \( +6.00 \mathrm{nC} \). Find the \( x \) - and \( y \)-components, the magnitude, and the direction of the electric field, \( \vec{E} \), at the following points:
(a) point A;
(b) point B;
(c) point C; and
(d) point D.
