An electric dipole coincides on Z-axis and its mid-point is on origin of the coordinates system. The electric field at an axial point at a distance z from origin is `E_((z))` and electric field at an equatorial point at a distance y from origin is `E_((y))`. Here, `z = y gt gt a`, so `|(E_((z)))/(E_((y)))| =`...

The correct Answer is:
D
`vecE_z=(2kvecp)/(z^3),vecE_y=(-Kvecp)/y^3=(-Kvecp)/z^3, ` [as z =y]
`|(vecE_z)/(vecE_y)|=2`
