One very long wire carries a current of 30A to the left along the x-axis.A second very long wire carries a current of 50A to the right along the line(y=0.280m,z=0)

Question

A)Where in the plane of the two wires is the total magnetic field equal to zero?
B)A particle with a charge of -2.00ìc is moving with a velocity of v=150 i mm/s along the line(y=0.100m,z=0)Calculate the vector magnitude force acting on the particle.
C)A uniform electric field is applied to allow the particle to pass through the region undeflected.Calculate the required vector electric field
