An electron enters a uniform magnetic field of 0,2 T perpendicularly with a velocity of . Given and , calculate the radius of its circular trajectory.
Answer and explanation
Correct answer: A.
- Step 1: Magnetic Lorentz force provides centripetal acceleration: . Step 2. m. Answer: 1,14 \times 10^{-4} m. Why not the others: Standard cyclotron radius formula gives m.
