Question

Write the mass,charge and e/m (charge/mass) ratio of electron, proton and neutron

Answer 1

Neutron has no charge, hence e/m is zero for neutron. Next, ∝-particle (He2+) has very high mass compared to proton and electron, therefore very small e/m ratio. Proton and electron have same charge (magnitude) but former is heavier, hence has smaller value of e/m. e/m : n < ∝ < p < e
Neutron has no charge an mass equals to proton. E/m equal to 0.
Proton has mass 1.67×10^-27. Charge =1.6×10^-19. E/m= 10^-8

Answer 2

Answer:

mass of electron -- 9.1 × 10^-31 kg

charge -- 1.6 × 10^-19 C

mass of proton -- 1.67 × 10^-27 kg

charge -- 1.6× 10^-19 C

mass of Neutron -- 1.67×10^-27 kg

charge --0

the charge of Neutron is 0 hence the e/m is also neutral

e/m ratio of electron is 1.78 × 10^8 C/g

e/m ratio of proton is 9.57 × 10^4 C/g
