📝 Short Description: The charge-to-mass ratio (𝑒/𝑚) of an electron can be derived from the motion of electrons in electric and magnetic fields. One such experimental relation is: 𝑒/𝑚 = 2𝑉/𝐵2𝑟2 Where: V = accelerating voltage B = magnetic field strength r = radius of the electron’s circular path This formula is used in physics experiments to determine fundamental properties of electrons.
The correct relation for the charge-to-mass ratio (e/m) of an electron is?
