A negative charge moving parallel to a 2 Tmagnetic field experienced a force of

Question

A negative charge moving parallel to a 2 Tmagnetic field experienced a force of 5 N.

Which one of the following best explains why the abovestatement is false?

Magnetic fields make charges move in circles so the charge couldn'tbe moving in a straight line.
F = qvBsin where is the angle between the velocityand the magnetic field. If the charge is moving parallel to themagnetic field then the angle between them is 0o, sin0o is 0, andthe force is 0 N.
Negative charges can't have a magnetic force exerted on thembecause they aren't metals.
W = (Fcos)s where is the angle between the force andthe velocity. If the charge is moving parallel to the magneticfield then the angle between the velocity & the force is 90oand cos(90o) is 0. Thus no work is done and as a result there mustbe no force on the charge.
The magnetic field must always be perpendicular to thevelocity.
N is not a unit of force. A negative charge moving parallel to a 2 Tmagnetic field experienced a force of 5 N.

Explanation / Answer

F = qvBsin where is the angle between the velocity and the magnetic field. If the charge is moving parallel to the magnetic field then the angle between them is 0o, sin0o is 0, and the force is 0 N.
