Two ideal electric dipoles A and B, having their dipole moment p1 and p2 respectively are placed on a plane with their centres at O as shown in the figure. At point C on the axis of dipole A, the resultant electric field is making an angle of 37$^\circ$ with the axis. The ratio of the dipole moment of A and B, ${{{p_1}} \over {{p_2}}}$ is : (take $\sin 37^\circ = {3 \over 5}$)

Question

Two ideal electric dipoles A and B, having their dipole moment p₁ and p₂ respectively are placed on a plane with their centres at O as shown in the figure. At point C on the axis of dipole A, the resultant electric field is making an angle of 37$^\circ$ with the axis. The ratio of the dipole moment of A and B, ${{{p_1}} \over {{p_2}}}$ is : (take $\sin 37^\circ = {3 \over 5}$)

${3 \over 8}$

${3 \over 2}$

${2 \over 3}$

${4 \over 3}$
