Solution

The correct options are
C A neutron does not exert electric repulsion
D Coulomb forces have longer range compared to nuclear forces
As the number of protons increases, Coulomb repulsive among protons increases. To compensate this repulsion, number of neutrons is increased.

Q. The heavier nuclei tend to have larger N/Z ratio because
(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 the nuclear forces.

Q. A free neutron decays to a proton but a free proton does not decay to a neutron. This is because
(a) neutron is a composite particle made of a proton and an electron whereas proton is a fundamental particle
(b) neutron is an uncharged particle whereas proton is a charged particle
(c) neutron has large rest mass than the proton
(d) weak forces can operate in a neutron but not in a proton.

Q. The heavier nuclei tend to have larger N/Z ratio because

Q. Inspite of mutual repulsion between the protons and no electric force between neutrons, a number of protons and neutrons do stay together to form stable nuclei. Which of the following are reasons for this?

1

. Another type of force, called nuclear force works between these particles when they are very close to each other

2

. The neutrons keep the protons apart so that there is no repulsion between them

3

. The nuclear force is always attractive and does not depend on the charge of the particles
Select the correct answer from the codes given.

Q. STATEMENT-1:
The plot of atomic number (y-axis) versus number of neutrons (x-axis) for stable nuclei shows a curvature towards x-axis from the line of

45^{o}

slope as the atomic number is increased.
STATEMENT-2:
Proton-proton electrostatic repulsions begin to overcome attractive forces involving protons and neutrons and neutrons in heavier nuclides.
