b.N,p,e,

c.N,p,,e

d.N,,p,e

Answer 1

Answer:

a)E,P,N

Explanation:

a. e, p, n,

b. n, p, e

c. n, p, e

d. n, p, e

Answers : (1)

Neutron has no charge, hence e/m is zero for neutron . Proton and electron have same charge (magnitude) but former is heavier, hence has smaller value of e/m. electron has the smaller Mass so it has the highest c/m ratio
