Question

A very long, straight wire carries a current of 28 A in the +k direction. An electron 1.6 cm from the center of the wire in the i direction is moving with a speed of 5.2 times 10^6 m/s. Find the force on the electron when it moves in the following directions. directly away from the wire N i You currently have 8 submissions for this question. Only 15 submission are allowed.

Explanation / Answer

B = uo*I/2pir

r = 1.6 cm = 1.6 x 10^-2 m

I = 28 A

B = 3.5 x 10^-4

F = qvB sintheta

since v and B is perpendicular so theta = 90

sin 90 =1

F = qvB

F = -2.912 x 10^-16 N

by right hand rule direction in j but here electron is negatively charge , direction in -j direction
