Question 14





Q14:One long wire carries current A to the left along the x axis. A second long wire carries current A to the right along the line (y = 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 22.00 mC is moving with a velocity of i ^ Mm/s along the line (y = m, z = 0). Calculate the vector magnetic force acting on the particle.
(c) What If? A uni- form electric field is applied to allow this particle to pass through this region undeflected. Calculate the required vector electric field.
