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?
A
The motion of the electron is uniformly circular with a period of 2πmₑ/(eB)
B
The trajectory of the electron is a circle with a radius of mₑv/(eB)
C
The motion of the electron is circular with constant angular velocity
D
The electron continues to move with a constant velocity v⃗
E
The motion of the electron is uniformly circular with a frequency eB/(2πmₑ)
