## Physics– Important Questions Bank for Tamil Nadu HSC 2016 Examination

We had mentioned some tips for cracking the HSC Tamil Nadu exam here: HSC Study Tips to Crack HSC Exams.

We had also shared Important Questions Bank for HSC Examination 2016 and students have really appreciated it and showered us with love last year.

Today, we are posting the Physics– Important Questions Bank for Tamil Nadu HSC 2016 Examination to make life easy for all you HSC students.

Without making you wait any further, please find the questions below:

1. With the help of a functional block diagram, explain the working of a super heterodyne AM receiver.
2. What is an operational amplifier? Explain its working as an inverting amplifier?
3. Describe the construction and working of a Bainbridge mass spectrometer in determining the isotopic masses
4. State the principle and explain J.J Thomson’s experiment in determining e/m of an electron.
5. On the basis of wave theory explain total internal reflection
6. Explain the principle, construction and working of a transformer. (Diagram not necessary) define its efficiency
7. Obtain an expression for magnetic induction due to an infinitely long straight conductor carrying current
8. What is an electrical dipole? Derive an expression for the electric field due to an electric dipole at a point along the equatorial line.
