Find CBSE Class 12th Physics Question Paper2014 set -2. Get the idea that what types of questions had been asked in the cbse class 12th board exam Physics question paper. The pattern in which the Question Paper is set is quite different from the manner in which the course structure is defined actually. Inspite of the predefined Course Curriculum, there are certainly some loop holes between the question paper formed and the content of the course. Henceforth, students need to identify these gaps and catch up where the textbooks left off, if they want to get acquainted with the examination pattern. This not only helps them prepare for exams in a better manner but also helps them in understanding the depth with which a topic should be studied.

Few Sample Questions from this paper are as follows:

Q. A biconvex lens made of a transparent material of refractive index 1.5 is immersed in water of refractive index 1.33. Will the lens behave as a converging or a diverging lens? Give reason.

Q. Estimate the average drift speed of conduction electrons in a copper wire of cross-sectional area 25 × l0–7 m2 carrying a current or 1n8 A. Assume the density or conduction electrons to be 9 × 1028 m–3.

Q. Show diagrammatically the behavior or magnetic field lines in the presence of (i) paramagnetic and (ii) diamagnetic substances. How does one explain this distinguishing feature?

Q. Draw a labelled diagram or van de Graff generator. State its working principle to show how by introducing a small charged sphere into a larger sphere, a large amount or charge can be transferred to the outer sphere. State the use of this machine and also point out its limitations.

If you have any Question/Point on the above information, please ask/discuss it in the CBSE Group.
