A charge q1 = 18.0 µC moves with a speed of 4.50 103 m/s perpendicular to a uniform magnetic field. The charge experiences a magnetic force of 7.41 10-3 N. A second charge q2 = 4.00 µC travels at an angle of 40.0° with respect to the same magnetic field and experiences a 1.80 10-3-N force. Determine
(a) the magnitude of the magnetic field and T
(b) the speed of q2. m/s
