Question

Two point charges qA=-6nC and qB are placed in vacuum. The charge qA is at a distance of 12cm from a point D. The charge qB is at distance 6cm from D. The resultant electric field vector Et created by the two charges at D is along x axis and makes 30 degrees with vector electric field of A and 60 degrees with Vector electric field of B. What is the magnitude of the electric field created by qB at D.
