These practice questions follow the AMERAT pattern: objective questions at Class 11 and 12 level from five subjects. They are written by our team to help you practise; the real paper has 20 questions from each subject. Try each question first, then open the answer.
Physics
1. What is the SI unit of force?
- Joule
- Newton
- Pascal
- Watt
Answer: B. Newton 1 newton is the force that gives a 1 kg mass an acceleration of 1 m/s².
2. A body moving with uniform velocity has an acceleration of:
- Zero
- Constant and positive
- Increasing
- Equal to g
Answer: A. Zero Uniform velocity means no change in speed or direction, so acceleration is zero.
3. A 10 Ω resistor is connected to a 5 V supply. The current is:
- 2 A
- 50 A
- 0.5 A
- 5 A
Answer: C. 0.5 A By Ohm’s law, I = V/R = 5/10 = 0.5 A.
4. The lift on an aircraft wing is mainly explained by:
- Archimedes’ principle
- Pascal’s law
- Bernoulli’s principle
- Hooke’s law
Answer: C. Bernoulli’s principle Faster airflow over the curved upper surface lowers pressure there, creating lift, as described by Bernoulli’s principle.

Answer: B. Oxidation Iron reacts with oxygen and moisture to form iron oxide, which is oxidation.
10. Which metal is the main element in alloys widely used in aircraft structures?
- Aluminium
- Lead
- Copper
- Zinc
Answer: A. Aluminium Aluminium alloys are light and strong, which is why they are widely used in airframes.
Mathematics
11. If sin θ = 3/5 and θ is acute, then cos θ is:
- 4/5
- 3/4
- 5/3
- 5/4
Answer: A. 4/5 cos θ = √(1 − 9/25) = √(16/25) = 4/5.
12. The derivative of x³ with respect to x is:
- x²
- 3x
- 3x²
- x⁴/4
Answer: C. 3x² d/dx (xⁿ) = n·xⁿ⁻¹, so d/dx (x³) = 3x².
13. The sum of the first 10 natural numbers is:
- 45
- 55
- 50
- 100
Answer: B. 55 n(n + 1)/2 = 10 × 11 / 2 = 55.
14. The value of log₁₀ 1000 is:
- 2
- 10
- 100
- 3
Answer: D. 3 1000 = 10³, so log₁₀ 1000 = 3.
