Q1PhysicsUnit 18: Atoms and Nuclei

Assertion It is not possible to use

^{35} C l

as the fuel for fusion energy. Reason The binding energy of

35 C l

is too small.

Q2PhysicsUnit 18: Atoms and Nuclei

Which of the following reasons make nuclear waste an extremely potent pollutant? This question has multiple correct options

Q3PhysicsUnit 18: Atoms and Nuclei

One of the characteristics of nuclear reactions is that in their decayed or fused parts

Q4PhysicsUnit 18: Atoms and Nuclei

Hydrogen bomb is based on

Q5PhysicsUnit 18: Atoms and Nuclei

Atomic mass of

_{6}^{13} C

is 13.00335 amu and its mass number is

13.0 .

If amu

=

931 \mathrm{MeV},

the binding energy of the neutrons present in the nucleus is

Q6PhysicsUnit 18: Atoms and Nuclei

In the process of nuclear fusion

Q7PhysicsUnit 18: Atoms and Nuclei

A nuclear fission is given below

A^{240} \rightarrow B^{100}+C^{140}+Q(\text {energy})

Let binding energy per nucleon

A, B

and

\mathrm{C}

7.6 \mathrm{MeV}, 8.1 \mathrm{MeV}

and

8.1 \mathrm{MeV}

respectively. Value of

Q

is :

Q8PhysicsUnit 18: Atoms and Nuclei

Results of calculations for four different designs of a fusion reactor using D-D reaction are given below. Which of these is most promising based on Lawson criterion?

Q9PhysicsUnit 18: Atoms and Nuclei

What parameter is used to measure the stability of a nucleus?

Q10PhysicsUnit 18: Atoms and Nuclei

Assertion The plot of atomic number

(y \text { -axis) } v s

number of neutrons

(x-

axis ) for stable nuclei shows a curvature towards

x-

axis from the line of

45^{\circ}

slope as the atomic number is increased. Reason Proton-proton electrostatic repulsion begins to overcome attractive forces involving proton and neutrons in heavier nucleides.

Q11PhysicsUnit 18: Atoms and Nuclei

Assume that the nuclear binding energy per nuclear

(B / A)

versus mass number

(A)

as shown in the figure. Use this plot to choose the correct choice

(s)

given below.

Q12PhysicsUnit 18: Atoms and Nuclei

Which source of energy is used in a nuclear power station to generate electrical energy?

Q13PhysicsUnit 18: Atoms and Nuclei

The mass defect per nucleon is called

Q14PhysicsUnit 18: Atoms and Nuclei

If mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should

Frequently asked questions

How long should a Binding energy per nucleon and its variation with mass number, nuclear fission and fusion mock test take?

For a topic-level test, aim for 20–30 minutes. For a full subject mock, allow 60–90 minutes to mirror JEE timing.

What is a good score on a Binding energy per nucleon and its variation with mass number, nuclear fission and fusion mock test?

Aim for 70%+ accuracy initially, then push toward 85%+ as your exam date approaches. Review explanations for every wrong answer.

Does Goodmarks score mock tests automatically?

Yes. Each MCQ is scored instantly with the correct answer and explanation shown after submission.

Can I retake the same mock test?

Pro users can generate new question sets by topic. Reattempting the same questions after a gap is excellent for retention.
