There is one short electric dipole place...

There is one short electric dipole placed on a horizontal plane. A circle is drawn assuming centre of dipole as centre of circle and plane of the circle is perpendicular to the axis of electric dipole. Thế number of points on this circle where electric field intensity due to electric dipole is perpendicular to the axis of dipole.

Text Solution

Verified by Experts

The correct Answer is:
0

The circle described in this question lies on the perpendicular bisector plane of electric dipole, where electric field intensity is anti-parallel to dipole moment vector. Hence, it cannot be perpendicular to the axis so, no point exists.

Electric Field Intensity Due To A Short Dipole At Some General Point

There is one short electric dipole placed on a plane. A straight line is drawn on this plane passing through the centre of electric dipole making an angle theta with the axis of dipole. A point P is selected on this line at a distance ten times the length of electric dipole from centre of electric dipole. Electric field intensity at the point P makes an angle alpha with the axis of electric dipole . What will be the magnitude of (tan theta)/(tan alpha) ?
