Two magnetic dipoles X and Y are kept at...

Two magnetic dipoles X and Y are kept at a distance d apart, with their axes perpendicular to each other. The dipole moment of Y is twice that of X. P is a point along the horizonal line which is at the midpoint of d. What is the magnitude of the force of particle of charge q passing through P at angle `theta=45^(@)`? (d is very much larger in comparison to dipole)

A

`sqrt2((mu_(0))/(4pi))(M)/((d//2)^(3))xqv`

B

`((mu_(0))/(4pi))(2M)/((d//2)^(3))xxqv`

C

`((mu_(0))/(pi))(M)/((d//2)^(3))xxqv`
