What to expect: This mock test covers key concepts from the System of Particles and Rotational Motion 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.Assertion (A): A rigid body can be in translational equilibrium yet not in rotational equilibrium. Reason (R): Vanishing of the total external force and vanishing of the total external torque are independent conditions.
- 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
-
2.For a system of two particles of equal mass placed on the x-axis, the centre of mass lies:
- A.at the heavier particle's position
- B.exactly midway between them
- C.at the origin always
- D.outside the line joining them
-
3.In X = (m1x1 + m2x2)/(m1 + m2), the quantity X is:
- A.the arithmetic mean of x1 and x2
- B.the mass-weighted mean of x1 and x2
- C.the geometric mean of the masses
- D.the harmonic mean of x1 and x2
-
4.From a uniform disc of radius R, a circular hole of radius R/2 is cut out, its centre at R/2 from the disc centre. The CM of the remaining body is at:
- A.R/6 from the centre, on the side opposite to the hole
- B.R/2 from the centre, on the side of the hole
- C.the centre of the original disc
- D.R/3 from the centre, on the side of the hole
-
5.![fig_6_31_flywheel.png]() For the cylinder in the figure (R = 20 cm) with the rope pulled at F = 25 N, the torque about the axis is:
- A.5 N m
- B.50 N m
