<span>The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field. This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero</span>

The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire. The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.

Answer:

false

Explanation:

Resultant is a force with the combined effect of two or more forces. Even though a force is a vector, it is not part of the definition of a vector. Vectors a made of 2 or more components, depending on the dimension of the vector. A 2-D vector has two components, 3-D has three, and so on. In your case, you are probably generally working on 2-D vectors, so simply two components would be correct.
