When at rest, a proton experiences a net electromagnetic force of magnitude 9.0×10−13 n pointing in the positive x direction. when the proton moves with a speed of 1.6×106 m/s in the positive y direction, the net electromagnetic force on it decreases in magnitude to 7.4×10−13 n , still pointing in the positive x direction find the magnitude of the magnetic field.
