The increasing order (lowest first) for ...

The increasing order (lowest first) for the values of q/m (charge/mass) for electrons (e) , proton (p), neutron (n) and alpha particles (`alpha`) is :

A

e, p,n, `alpha`

B

n, p, e, `alpha`

C

n, p, `alpha` , e

D

n, `alpha` ,p, e

Text Solution

Verified by Experts

The correct Answer is:
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`
