Super 20 Sample Paper Physics Class 12

About Super 20 Sample Paper Physics Class 12

Super 20 Physics Sample Paper for class 12 is designed in accordance with the pattern specified by the CBSE for the Examination. This book consists of 20 Solved Different types of questions. These papers give you an idea about how your real Board Examination Question Paper will look in terms of difficulty level, marks distribution, sections, number & type of questions, time and duration.

Why to Practice Super 20 Physics Sample Paper?

Super 20 Physics Sample Papers help you to get into the real exam-type feeling. As this question paper is exactly similar to the CBSE sample papers, you will find it very useful to analyze how much time you need to answer each question, what should be your writing strategy and how to finish it in given time. The more you practice, the more efficiency level you achieve. It matters a lot. Most of the time, you know the answers but you miss it only because of bad time management.

Students are advised to solve all these Sample Papers and refer their answers to the Marking Scheme to assess their level of preparation for CBSE Board Examination. All these questions are very important for forthcoming CBSE Board Examination.

Some Questions from Super 20 Sample Paper Physics Class 12

  1. Four nuclei of an element fuse together to form a heavier nucleus. If the process is accompanied by release of energy, which of the two — the parent or the daughter nucleus would have a higher binding energy/nucleon? (1)

  2. What is the angle between the directions of electric field at any (i) axial point and (ii) equatorial point due to an electric dipole? (1)

  3. A partially plane polarised beam of light is passed through a polaroid. Show graphically the variation of the transmitted light intensity with angle of rotation of the polaroid. (1)

  4. Calculate the ratio of energies of photons produced due to transition of electron of hydrogen atom from its, second permitted energy level to the first level, and highest permitted energy level to the second permitted level. (2)

  5. Write the relation between the angle of incidence (i), the angle of emergence (e), the angle of prism (A) and the angle of deviation (d) for rays undergoing refraction through a prism. What is the relation between ∠i and ∠e for rays undergoing minimum deviation? Using this relation, write the expression for the refractive index (m) of the material of a prism in terms of A and the angle of minimum deviation (dm). (3)
