Step 1 . At axial point of dipole
Electric field = E=2kpr3
Step 2 , At equitorial position (perpendicular bisector)
Step 3 ,Finding ratio of step1 to step 2
Ratio = 2
Final answer is Ratio = 2
Electric field at a point due to an electric dipole on an axis inclined at an angle theta <90° to the dipole axis is perpendicular to the dipole axis if the angle theta is
