Photoelectric EffectHard
Question
The heavier stable nuclei tend to have larger N/Z ratio because -
Options
A.a neutron is heavier than a proton
B.a neutron is an unstable particle
C.a neutron does not exert electric repulsion
D.Coulomb forces have longer range compared to nuclear forces
Solution
As the number of protons increases, Coulomb repulsive force among protons increases. To compensate, number of neutrons which are neutral is increased.
