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) is
a) e ,p ,n ,α b) n ,p ,e ,α c) n, p, α, e d) n, α, p, e

Answer 1

the correct answer is neutron,alpha,proton,electron
so,d is correct

Answer 2

ANSWER:

neutron has no charge e/m(charge/mass) is zero for neutron alpha particle has very high mass compared to proton and electron therefore very small e/m ratio of proton and electron have same charge but former is heavier .hence,has smaller value of e/m is

n→α→p→e.
