Question

5. The currents l, and I are flowing as shown. What is the magnitude and the direction of the net magnetic field created by these two currents at the location P. What would be the velocity of qw2uc, at location P such that the magnetic force on q to be 4x10-N and which points in the positive y-direction 19 m P642) 1 + I , = 2A I=64 F M(sy)
