Question

Imagine an electron moving in a uniform 0.25 T magnetic field; its velocity components parallel and perpendicular to the field are both 3.1 Mm/s. With a speed of 4.38Mm/s and a radius of 71um. How far does it move along the field direction in the time it takes to complete a full orbit about the field?

Step 1

Given that the speed of the electron is 4.38 Mm/s and the radius of the orbit is 71 um, we can use the formula for the period of a circular motion: T = 2πr / v T = 2 * π * (71 * 10^-6 m) / (4.38 * 10^6 m/s) T ≈ 3.23 * 10^-5 s Show more…
