Determine the magnitude of thenbsperarr field at a point 30

Question

A +4.0 10^-9C charged object is 4.0cm along a horizontal line toward the right of a -3.0 x 10^-9C charged object

Determine the magnitude of the E^→ field at a point 3.0 cm directly above the negative charge?

Determine the direction of the E^→ field at a point 3.0 cm directly above the negative charge? In terms of θ.
