A uniform magnetic field of B = 3x10−4 T points in the positive x direction. A charge of 6 μC is fixed at the origin and a charge of −3μC is fixed at (2,0) on the x axis. A charge of 4 μC travels on the y axis at 5.0 x 106 m/s. Neglecting gravity, what force does the moving charge experience when it is 6.0 nm above the origin? Give your answer as a vector (that is, with both magnitude and direction).
