Three (3) Electrical dipoles of magnitude p=1.210^9 Cm each are lined up along, say x-coordinate axis pointing in the positive direction.

Three (3) Electrical dipoles of magnitude p=1.2×10^−9 C⋅m each are lined up along, say x-coordinate axis pointing in the positive direction. Place one dipole at the coordinate origin and the other two, one to the left and the other to the right. Let dipoles be 2 μm apart.

Determine the strength and the direction of the electrical field at x = 0.5 cm.
