An electron follows a helical path in a uniform magnetic field given by B = (20i

Question:

An electron follows a helical path in a uniform magnetic field given by B = (20i – 50j - 30k)mT. At time t = 0, the electron's velocity is given by v = (20i – 30j + 50k) m/s.

(a) What is the angle Φ between v and B? The electron's velocity changes with time. Do

(b) Its speed and

(d) What is the radius of the helical path?
