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.Using 1 u = 931.5 MeV/c^2, the energy equivalent of a mass of 2 u is:
- A.465.75 MeV
- B.931.5 MeV
- C.1863 MeV
- D.3726 MeV
-
2.For the reaction C-12 + C-12 -> Ne-20 + He-4 with m(C-12) = 12.000000 u, m(Ne-20) = 19.992439 u, m(He-4) = 4.002603 u, the Q value is about +4.6 MeV. The reaction is:
- A.Endothermic
- B.Exothermic
- C.Q = 0
- D.Impossible
-
3.The mass defect of the O-16 nucleus is 0.13691 u. Expressed in energy units (1u = 931.5 MeV/c^2), the energy needed to separate it into its constituents is about:
- A.127.5 MeV
- B.931.5 MeV
- C.13.7 MeV
- D.16.0 MeV
-
4.Assertion (A): The binding energy per nucleon is nearly constant in the range 30 < A < 170. Reason (R): The nuclear force is short-ranged, so a nucleon interacts only with its nearest neighbours (saturation).
- 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
-
5.The binding energy of an iron-56 nucleus is about 492 MeV. Its binding energy per nucleon is approximately:
- A.4.4 MeV
- B.7.1 MeV
- C.8.8 MeV
- D.9.8 MeV
