Question

The time period of a charged particle undergoing circular motion in a uniform magnetic field is independent of its

• A. Speed
• B. Mass
• C. Charge
• D. Magnetic induction

Answer 1

The correct option is A Speed

Time period of a charged particle undergoing uniform circular motion in a uniform magnetic field is given by,
$T=\frac{2\pi m}{qB}$ where, m = mass, q = charge and B = magnetic field.
Thus, the time period is independent of the speed of the charged particle.
Hence, the correct answer is option (1).
