Question

One long wire carries current 12.0 A to the left along the x axis. A second long wire carries current 64.0 A to the right along = 0.280 m, z = 0). the line (y (a) Where in the plane of the two wires is the total magnetic field equal to zero? y -.0646 m (b) A particle with a charge of -2.00 HC is moving with a velocity of 150î Mm/s along the line (y 0.100 m, z = 0). Calculate the vector magnetic force acting on the particle. (Ignore relativistic effects.) =-0.028 (c) A uniform electric field is applied to allow this particle to pass through this region undeflected. Calculate the required vector electric field. 14266.65 N/C X
