Two magnetic dipoles X and 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 θ = 45° 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)

A proton goes undeflected in a crossed electric and magnetic field (the fields are perpendicular to each other) at a speed of 2.0 x 10^5m/s. The velocity is perpendicular to both the fields. When the electric field is switched off, the proton moves along a circle ol radius 4.0cm. Find the magnitudes of the electric and the magnetic fields. Take the mass of the proton = 1.6 x 10^-27kg.
