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

Answer» Correct Answer - D
e/m value for
neutron (0/1)=0
`alpha`-particle (2/4)=0.5
proton (1/1)=1
electron `((1)/(1//1837))=1837`. ltbtgt `:.` (d) represents the correct increasing order.
