Question

Order of q/m ratio of proton, α⁻ particle and electron is(a) e > p >α
(b) p >α > e(c) e > α > p(d) None of these

Answer 1

The mass number of the proton is 1 while that of an a-particle is 4

and that of an electron is comparatively negligible. Also, both the

proton and electron have 1 unit of atomic charge and that of the

a-particle is 2 units. so q/m must be in the order of electron,

proton, and a-particle.
