An electron with an initial velocity enters an evacuated region with a uniform m

Question

An electron with an initial velocity enters an evacuated region with a uniform magnetic field . Directed into the page. The velocity of the electron is perpendicular to the magnetic field a shown. Ignoring the gravitational force, how many forces act on the electron after it enters this region? One the force of the electron's initial velocity. One, the magnetic force. Two , the force of the electron's initial velocity and the magnetic force. Two , the electric force due to the charge of the charge of the electron and the magnetic force. No force acts on the electron. In the situation described in the preceding problem, which one of the following sketches best represents the path the electron will take upon entering the region with the magnetic field directed into the page?
