Question

write the approximate value of the following :
(i) m(neutron)/m(electron)
(ii) r(atom)/r(nucleus)​

Answer 1

Answer:

1. 0.183 × 10^4

2. 10^4 is correct

because mass of neutron is 1.67× 10^-27 kg and mass of electron is 9.1×10 ^-31 kg

radius of atom is 10^-10 m and radius of nucleus is 10^-14m.
