Question

Q2 The increasing order(lowest first ) for the values of e/m (charge/mass) for electron (e),proton(p),neutron(n) and alpha(α) isa) e ,p ,n ,α
b) n ,p ,e ,α
c) n, p, α, e
d) n, α, p, e

​

Answer 1

Answer:

D=n,à,p,e

Explanation:

Increasing order (lowest first) for the values of e/m (charge / mass) for electron (e), proton (p), neutron (n) and α-particle (α) is n,α,p,e

e/m for neutron =10=0

e/m for alpha particle =42=0.5

e/m for proton =11=1

e/m for electron =(18501)1=1850

Note: e is the charge of the particle, m is the mass of a particle and the mass of an electron is 18501 times the mass of proton.

Hence, the correct option is D
