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

The correct Answer is:
B
On the axis of dipole `=int_(0)^(2pi)lambdaa d theta`
`=int_(0)^(2pi)cos^(2)theta d theta =alambda_(0)pi =pialambda_(0)`
