Column I gives a situation in which two dipoles of dipole moment p 
and 
are placed at origin. A circle of radius R with centre at origin is drawn as shown in figure. Column II gives coordinates of certain positions on the circle. Match the statements in Column I with the statements in Column II .
Column I | Column II | ||
(A) | The coordinate(s) of point on circle where potential is maximum: | (P) | |
(B) | The coordinate(s) of point on circle where potential is zero: | (Q) | |
(C) | The coordinate(s) of point on circle where magnitude of electric field intensity is : | (R) | |
(D) | The coordinate(s) of point on circle where magnitude of electric field intensity is : | (S) |

(P) - (R, S) - (P, Q) - (R, S)
Sol. The resultant dipole moment has magnitude 
= 2P at an angle θ = tan -1 
= 60° with positive x direction.
Diameter AB is along net dipole moment and diameter CD is normal to net dipole moment.
\ Potential at A 
is maximum
Potential is zero at C 
and D 
Magnitude of electric field is 
at A 
and B 
Magnitude of electric field is 
at C 
and D
