JEE Main 2 April 2026, Shift 1, Physics Q36

Question 36 of 75 in this shift, Physics question 11 of 25, Section A.

Two short electric dipoles AA and BB having dipole moment p1p_1 and p2p_2 respectively are placed with their axis mutually perpendicular as shown in the figure. The resultant electric field at a point xx is making an angle of 60∘60^\circ with the line joining points O and xx. The ratio of the dipole moments p2/p1p_2/p_1 is __________.

The figure, in words

Dipole A lies along the horizontal axis (+ charge at left end) and dipole B along the vertical axis (+ at top, - at bottom), both centred at O; point x lies on a dashed horizontal line to the right of O.
