Question 3

A uniform circular disc of radius 0.5 m and mass 3 kg is rotating about its central axis with an angular velocity of 10 rad/s. If the radius is increased to 0.75 m without changing the mass distribution, what will be the new angular velocity? (Assume conservation of angular momentum)

Accepted Answer

A. 4.44 rad/s — Angular momentum L = Iω is conserved. For a disc, I = ½mr², so ω₂ = (I₁/I₂) * ω₁ = (r₁²/r₂²) * ω₁ = (0.5²/0.75²) * 10 ≈ 4.44 rad/s. Option A (4.44 rad/s) is correct. Option B (6.67 rad/s) results from using diameter instead of radius. Option C (10.00 rad/s) assumes no change. Option D (15.00 rad/s) is a miscalculation of the ratio.

Answer

B. 6.67 rad/s

Answer

C. 10.00 rad/s

Answer

D. 15.00 rad/s

Question 4

A newly enacted state law mandates compulsory registration for all religious organizations, with non-compliance leading to severe penalties. Several organizations challenge this law in the High Court, alleging it infringes upon their fundamental right to freedom of religion. In this context, which of the following accurately describes the High Court's potential action?

Accepted Answer

B. The High Court can review the law and, if it finds the law inconsistent with fundamental rights, declare it ultra vires the Constitution. — The High Courts, under Articles 226 and 227, possess the power of judicial review to examine the constitutionality of legislative enactments. If a state law is found to violate fundamental rights, the High Court can declare it ultra vires (beyond the powers) the Constitution, thereby striking it down. The Supreme Court also exercises this power, but High Courts are not precluded from doing so for state laws.

Answer

A. The High Court must refer the matter to the Supreme Court as only the apex court can rule on the constitutionality of a state law impacting fundamental rights.

Answer

C. The High Court can only recommend amendments to the state legislature but cannot strike down the law itself.

Answer

D. The High Court's jurisdiction is limited to procedural irregularities, not the substantive content or constitutional validity of a legislative act.
