Two magnetic dipoles $\displaystyle X$ and $\displaystyle Y$ are placed at a separation d, with their axes perpendicular to each other. The dipole moment of Y is twice that of X. A particle of charge q is passing through their midpoint P, at angle $\displaystyle \theta=45^{\circ}$ with the horizontal line, as shown in figure. What would be the magnitude of force on the particle at that instant ? (d is much larger than the dimensions of the dipole)
