Question

The increasing order for the values of e/m (charge/mass) for electron (e), proton (p), neutron (n) and alpha particle (α) is

Answer 1

ANSWER:

neutron (n) has no charge e/m(charge/mass) is zero for neutron alpha (∝) particle has very high mass compared to proton(p) and electron (e)therefore very small e/m ratio of proton and electron have same charge but former is heavier .hence,has smaller value of e/m is

n→∝→p→e.
