One long wire carries current 24.0 a to the left along the x axis. a second long wire carries current 70.0 a to the right along the line (y-0.280 m, z 0) (a) where in the plane of the two wires is the total magnetic field equal to zero? (b) a particle with a charge of-2.00 ? ? is moving with a velocity of 150? mm/s along the line (y = 0.100 m, z = 0). calculate the vector magnetic force acting on the particle. (ignore relativistic effects.) (c) a uniform electric field is applied to allow this particle to pass through this region undeflected. calculate the required vector electric field n/c
