ICSE Class 10 Nuclei — Mock Test (2027)
Free online mock test for Nuclei (ICSE Class 10 Physics) — 72 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Nuclei chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.The constancy of the binding energy per nucleon in the range 30 < A < 170 is a consequence of the fact that the nuclear force is:
- A.Long-ranged
- B.Short-ranged (saturated)
- C.Repulsive at all distances
- D.Charge dependent
-
2.Assertion (A): The density of nuclear matter is the same for all nuclei, independent of mass number A. Reason (R): Both the mass and the volume of a nucleus are proportional to A.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
3.The value of the constant R0 in the nuclear radius formula R = R0 A^(1/3) is about:
- A.1.2 x 10^-10 m
- B.1.2 x 10^-15 m
- C.1.2 x 10^-12 m
- D.1.2 x 10^-9 m
-
4.Fusion of hydrogen nuclei into helium nuclei is the source of energy of:
- A.Nuclear reactors on Earth
- B.All stars including our Sun
- C.Chemical combustion
- D.Radioactive decay only
-
5.A nucleus with A = 240 (Ebn about 7.6 MeV) splits into two nuclei each with A = 120 (Ebn about 8.5 MeV). The reason energy is released is that the products are:
- A.Less tightly bound than the parent
- B.More tightly bound (higher binding energy per nucleon) than the parent
- C.Lighter in total rest mass of nucleons
- D.Electrically neutral
