- An electron in motion with a constant velocity v⃗ enters a uniform magnetic field B perpendicularly. Given that mₑ, e, v represent the mass, charge, and magnitude of the electron's velocity respectively, which of the following statements is false?
- AThe motion of the electron is uniformly circular with a period of 2πmₑ/(eB)
- BThe trajectory of the electron is a circle with a radius of mₑv/(eB)
- CThe motion of the electron is circular with constant angular velocity
- DThe electron continues to move with a constant velocity v⃗
- EThe motion of the electron is uniformly circular with a frequency eB/(2πmₑ)
