NCERT 4.10 - Moving Charges and Magnetism
Question: In a chamber, a uniform magnetic field of 6.5 G is maintained. An electron is shot into the field with a speed of 4.8×10⁶ m/s normal to the field. Explain why the path of the electron is a circle. Determine the radius of the circular orbit.
Answer: Radius = 4.2 cm (Path is circular due to transverse magnetic force)
