Question

A charged particle moving with velocity v⃗ is subjected to a magnetic field B⃗, and the magnetic force on it is nonzero. This implies that:

G1 Physics · Accepted Answer

Step 1: Magnitude of magnetic force is F = |q|vB sinθ. Step 2: F ≠ 0 requires sinθ ≠ 0. Step 3: Thus θ may be any angle except 0° and 180°; choose D. Final answer: (D) the angle may have any value other than 0° or 180°.
