A particle having charge 2.90 C moves via a uniform magnetic field. At one instant the velocity of the particle is around (3.50i + 2.50j + 4.00k) m/s and the magnetic force on the particle is around (8.70i - 26.1j + 8.70k) N. The x and y components of the magnetic field are equivalent. Determine (i) the x-component, (ii) the y-component and (iii) the z-component of B?
