Question

Neutron is preferred to a proton for bombarding atomic nucleus because –

• A. Neutron is smaller than a proton
• B. Neutron weighs less than a proton
• C. Neutron has no charge
• D. Neutron can be obtained from nucleus

Answer 1

Answer: (C)

Neutron has no charge

Answer 2

Since proton is positively charged it suffers repulsion from nucleus and it requires larger kinetic energy of proton to bombard the nucleus. Since neutron is neutral it does not suffer such repulsion and less energy is required
