Answer 2

e/m has a special name : SPECIFIC CHARGE

• In the term e/m , the word "e" represents the charge of a subatomic particle, "m" represents the mass of the subatomic particle.

• This e/m has specific value for each of the subatomic particles.

• The direct value of e/m has found its uses in various mathematical equations.

• The SI unit of this quantity is Coulomb/kg.

• e/m for electron is 1.75 × 10¹¹ C/kg.

• e/m for proton is 9.6 × 10⁷ C/kg.

• e/m for neutron is zero , because charge of neutron is zero.

• The value of e/m is useful when we try to find out the Lorentz acceleration experienced by a charge when moved in a magnetic field.
