ICSE 2017 Physics Question Paper for Class 10

About this paper

This is ICSE Class 10 Physics, Science Paper 1, from the 2017 examination, code T17 521. It consists of 6 printed pages and carries 80 marks, with two hours to write after 15 minutes of reading. Section I, Questions 1 to 4, is compulsory. Each question has five two-mark parts, on forces and gravity, the jack screw, heat capacity, refraction and total internal reflection, the audible range, specific resistance, a bulb, the transformer, thermions and radioactivity. Section II, Questions 5 to 10, asks for any four questions, with a half-metre rule, pulley systems, calorimetry, lenses, damped vibrations and household wiring. Answers are to be written on a separate sheet. This copy has the questions only.

Questions from this paper

1. The distance between two bodies is doubled. How is the magnitude of the gravitational force between them affected?
2. If the power of a motor is 100 kW, at what speed can it raise a load of 50,000 N?
3. A solid of mass 50 g at 150°C is placed in 100 g of water at 11°C, and the final temperature is 20°C. Find the specific heat capacity of the solid. Specific heat capacity of water = 4.2 J/g°C.
4. The human ear detects sounds from 20 Hz to 20,000 Hz. Taking the speed of sound in air as 330 m/s, calculate the wavelengths of these extreme frequencies.
5. An electric bulb of resistance 500 Ω draws a current of 0.4 A. Calculate the power of the bulb and the potential difference at its ends.
6. A wire of length 80 cm has a frequency of 256 Hz. Calculate the length of a similar wire under the same tension which will have a frequency of 1024 Hz.
