Question

A long straight horizontal wire carries a current I = 1.80 A to the left. A positive 1.00 C charge moves to the right at a distance 5.00 m above the wire at constant speed v = 1250 m/s . (Figure 1) What are the magnitude and the direction of the magnetic force on the charge? What is the magnitude B of the magnetic field at the location of the charge due to the current-carrying wire? Express your answer in teslas.

Answer 1

Force on charge is 9 x 10^(-5) N above the wire6abd away from the wire.

The magnetic field at the location is 7.2 x 10^(-8) T inside the plane of paper.
