Question

When a charged particle moving with velocity is subjected to a magnetic field of induction $\vec { B }$ , the force on it is non-zero. This implies that-

• A. Angle between and $\vec { B }$ is either zero or 180⁰
• B. Angle between and is necessarily 90⁰
• C. Angle between and $\vec { B }$ can have any value other than 90⁰
• D. Angle between and can have any value other than zero and 180⁰

Answer 1

Answer: (D)

Angle between and can have any value other than zero and 180⁰

Answer 2

Q F = qvB sin q F = 0, if q = 0⁰ or 180⁰
