In 3.1 µs, an electron moves 20 cm in the direction of a 0.14 T magnetic field. The electron's velocity components perpendicular and parallel to the field are equal.
(a) What is the length of its actual spiral trajectory? it's not 1.64e-3cm or 40cm or 2.62e-10cm or 1.64e-3cm
part b is correct it's 12131
