The radius of the orbit of an electron moving with a speed of 10⁸ m/s perpendicular to a magnetic field of 5.0 × 10^-3 T is approximately

Question

Quizplus · Accepted Answer

The radius of the orbit can be calculated using the formula r = mv/qB. Using the given values: m (mass of electron) = 9.11 × 10^-31 kg, v = 10^8 m/s, q (charge of electron) = 1.6 × 10^-19 C, and B = 5.0 × 10^-3 T, the radius r is approximately 0.11 m.
