Priyanka Goyal | Re: Physics Questions For NTSE NTSE (National Talent Search Examination) is a national-level scholarship program in India. It is considered as the most prestigious and the most difficult examination at high school level in the country. The Physics Question Paper of the NTSE Examination is given below Q1. A sheet of paper is placed on a table and a jug full of water is kept on it while pulling the paper suddenly, it is observed that the water does not spill out of jug. It is due to the inertia of the (a) paper sheet (b) jug & water in it (c) hard (d) table Ans. (b) Q2. “Every Action has equal & opposite reaction” was discovered by (a) Pascal (b) Newton (c) Edison (d) Copernicus Ans. (b) Q3. If a car travels a distance of 100 km & it takes 25 minutes to reach its destination , the speed of the car is (a) 4 km/min (b) 4 mt/min (c) 400 mt/min (d) None of these Ans. (a) Q4. Name of scienctist who gave a relationship between mechanical energy & heat energy (a) Darwine (b) Jameswatt (c) James precot joule (d) sir Isac Newton Ans. (c) Q5. A 1500 w electric geyser used every day for 2 hrs. Calculate the energy consumed ? (a) 90 kwh (b) 30 kwh (c) 750 kwh (d) None of these Ans. (a) Power of Geyser = 1500 W Used time = 30 x 2 = 60 Energy Power x Time = 1500 x 60 / 1000 = 90 kwh Q6. As per Law of Conservation of energy during a process or system of transformation of energy, the energy is (a) always lost (b) always gained (c) (c) neither gain nor lost (d) (d) only gets converted for heat to mechanical energy Ans. (c) Q7. An engine supplies 196 joules of energy. If the energy is supplied to a weight of 500 gms. How high can it be lifted (a) 38.2 (b) 39.2 (c) 40.2 (d) 42 Ans. (b) Energy supplied to the engine = 196 J Mass of water = 500 gm = 500/1000 = ½ kg Acceleration due to ground (g) = 10 mt/sec2. Energy required for lifting water = mgh H = energy supplied / m x g = 196 x 2 / 1 x 10 = 39.2 mt. Q8. Which of the following force is responsible for taking a gas ballon upwards ? (a) Gravitational force (b) Muscular force (c) Bouyant force (d) Magnetic force Ans. (c) Q9. When white light is passed through a prism, it is observed that violet light bends more than the red light. This is because (a) Velocity of red light in glass is less than that of violet light (b) Refractive Index of glass is more for violet light (c) wave length of violet light is less than that of red light (d) It is the properties of these colours. Ans. (b) Q10. Pascal’s law hold good for (a) gases only (b) liquid & fluid (c) solids only (d) for all Ans. (d) Q11. The Instrument for measuring electric current is known as (a) Ammeter (b) Voltameter (c) Galvanometer (d) Chronometer Ans. (a) Q12. Find at what temperature, the velocity of sound in air is 1.5 times the velocity at 700 C (a) 357°C (b) 387°C (c) 350°C (d) 290°C Ans. (a) Q13. If m1 & m2 be the masses of two bodies, d be the distance between them, the force of attraction(F) as per the universal law of gravitation is Q14. The acceleration due to gravity is zero at (a) Poles (b) equator (c) center of earth (d) None of these Ans. (c) Q16. The size of an atom is nearly (a) 10 – 5 m (b) 10 – 8 m (c) 10 – 15 m (d) 10 – 10 m Ans. (d) Q17.
