Question

An electron is moving with a velocity 10^7 m/s at a perpendicular distance

Answer 1

An electron is moving at 6 x 107 m/s at a distance of 50 mm from a long straight wire carrying a current of 40 A. Find the magnitude and direction of the force on the electron when it is moving parallel to the wire (a) in the same direction as the current and (b) in the opposite direction to the current.
