Calculate the magnitude & direction of net electric field at origin due to these two point charges

A point charge q1 = -4.00 nC is at the point x = 0.60 m, y = 0.80 m , and a second point charge q2 = +6.00 nC is at the point x = 0.60 m , y = 0.

Calculate the magnitude of the net electric field at the origin due to these two point charges.

Calculate the direction of the net electric field at the origin due to these two point charges.
