Sample Tamil Nadu HSE First Year Physics Practice Questions

Try these sample questions to test your Tamil Nadu HSE First Year Physics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The SI base unit of luminous intensity is the:
A.candela
B.lumen
C.lux
D.watt
Explanation: The seven SI base units include the candela (cd) for luminous intensity. Lumen and lux are derived photometric units; watt is the SI unit of power.
2Dimensional formula of force is:
A.[MLT⁻²]
B.[MLT⁻¹]
C.[ML²T⁻²]
D.[MT⁻²]
Explanation: Force F = ma, so [F] = [M][LT⁻²] = [MLT⁻²]. This is also the dimension of weight and of thrust.
3Which of the following is a dimensionless quantity?
A.strain
B.stress
C.Young's modulus
D.surface tension
Explanation: Strain is change in length divided by original length (or analogous ratios), so it is dimensionless. Stress, Young's modulus, and surface tension all have dimensions involving force and length.
4If the percentage errors in measurement of mass and speed are 2% and 3% respectively, the maximum percentage error in kinetic energy (½mv²) is:
A.8%
B.5%
C.6%
D.11%
Explanation: KE = ½mv² ⇒ (ΔKE/KE)×100% = (Δm/m)×100% + 2(Δv/v)×100% = 2% + 2×3% = 8%. Errors multiply by the power of each factor.
5A physical quantity is given by X = a²b³/c. The percentage errors in a, b and c are 1%, 2% and 3% respectively. The maximum percentage error in X is:
A.11%
B.6%
C.8%
D.14%
Explanation: ΔX/X = 2(Δa/a) + 3(Δb/b) + 1(Δc/c) = 2(1%) + 3(2%) + 3% = 2+6+3 = 11%.
6The number of significant figures in 0.000520 is:
A.3
B.6
C.2
D.4
Explanation: Leading zeros after the decimal are not significant; they only locate the decimal point. Digits 5, 2 and the trailing 0 (after a non-zero digit in a decimal) give three significant figures: 5.20 × 10⁻⁴.
7Which pair of quantities has the same dimensions?
A.work and torque
B.force and energy
C.momentum and power
D.pressure and force
Explanation: Work = F·s and torque τ = r×F both have dimensions [ML²T⁻²]. They are different physical quantities but share dimensions.
8A student measures the diameter of a wire as 0.56 mm using a screw gauge of least count 0.01 mm. The percentage error in the measurement is approximately:
A.1.8%
B.0.01%
C.0.56%
D.3.6%
Explanation: Absolute error is taken as the least count 0.01 mm. Percentage error = (0.01/0.56)×100% ≈ 1.79% ≈ 1.8%.
9If force (F), acceleration (A) and time (T) are taken as fundamental quantities, the dimensions of mass are:
A.[F A⁻¹]
B.[F A T]
C.[F A⁻¹ T]
D.[F⁻¹ A]
Explanation: From F = mA, m = F/A, so [m] = [F A⁻¹]. Time is not required once force and acceleration define mass.
10A body starts from rest and moves with constant acceleration 2 m s⁻². Distance travelled in the 5th second is:
A.9 m
B.10 m
C.25 m
D.50 m
Explanation: Distance in nth second: sₙ = u + a(n − ½). With u=0, a=2, n=5: s₅ = 0 + 2(5 − 0.5) = 2×4.5 = 9 m. Alternatively s(5)−s(4) = ½a(25−16) = a×4.5 = 9 m.
