Question

The increasing order (lowest first) for the values of `e//m` (charge//mass) for electron `(e)`, proton `(p)`, neutron `(n)`, and alpha particle `(alpha)` is
A. `e,p,n,alpha`
B. `n,p,e,alpha`
C. `n,p,alpha,e`
D. `n,alpha,p,e`

Answer 1

Correct Answer - D
`e/m` for (i) neutron =`0/1`=0
(ii)`alpha`-particle=`2/4=0.5`
(iii)proton=`1/1` =1
(iv)electron=`1/(1//1837)=1837`
