One long wire carries current 20.0 A to the left along the x axis. A second long wire carries current 80.0 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 µC 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.
