8 An unpolarized light beam strikes glass at Brewster’s angle. Then:
Correct Answer: D
Explanation: At Brewster’s angle, reflected light is fully polarized (parallel to surface), while refracted light is partially polarized.
9 The moment of inertia of a 400 g rod about its perpendicular bisector is 2400 g cm². Its length is nearly:
Correct Answer: A
Explanation: For a thin rod: \(I = \frac{ML^2}{12}\). Solving gives \(L ≈ 8.5 \, \text{cm}\).
10 A thin disc (radius 4.5 cm) placed on water (surface tension 0.07 N/m) requires an excess force to lift it:
Correct Answer: A
Explanation: Force = surface tension × circumference: \(F = 0.07 × 2π × 0.045 ≈ 0.0198 \, \text{N} = 19.8 \, \text{mN}\).
11 In the thermodynamic cycle abcda, the work done by gas along path bc is:
Correct Answer: A
Explanation: Path bc is isochoric (constant volume), so work done \(W = PΔV = 0\).
12 A rolling bullock cart wheel (linear speed v) has points P (top) and Q (bottom). Which statement is correct?
Correct Answer: B
Explanation: Due to rolling motion: \(v_P = v + Rω = 2v\), \(v_Q = v - Rω = 0\). Thus, P moves faster.
13 A planet has mass \(\frac{1}{10}\) of Earth and diameter half of Earth. Its gravitational acceleration is:
Correct Answer: D
Explanation: \(g_{planet} = \frac{G(M/10)}{(R/2)^2} = \frac{4}{10}g_{Earth} = 3.92 \, \text{m/s}^2\).
14 The equivalent capacitance between terminals A and B in the given circuit is:
Correct Answer: A
Explanation: The circuit reduces to parallel and series combinations, resulting in 2 µF.
