The magnitude of electric field intensity at point (2,0,0)m due to a short dipole of dipole moment, P→=i^+3j^ coulomb metre kept with its centre at origin is _____ NC−1(Take14πε0=K)

tanθ=PyPx=31 θ=60° P=12+32=2 r=2The dipole moment makes an angle 600 with X− axis and lies in X−Y  plane as shown in figure. The electric field at point A due to dipole isE=kPr31+3cos2θ where θ=600∴E=7K8
