These questions will not only help the students to prepare for exams in a better manner, but will also help them in understanding the depth with which a topic should be studied.

**Few sample questions from the Question Paper are given below:**

**Q.** Explain the effect of solute on the surface tension of liquid?

**Q.** What is the Bulk modulus for a perfect rigid body?

** Q. **The free surface of oil in a tanker, at rest, is horizontal. If the tanker starts accelerating the free surface of oil will be titled by an angle and the acceleration is a ms-2 then, find the slope of the free surface?

** Q. **One day Hariom’s little brother was crying. He took a piece of camphor and put it in water. By seeing the camphor piece dancing on the surface of water, his little brother stopped crying.

**(a)** Why do small piece of camphor dance on the surface of water?

**(b)** What qualities you observed in Hariom?

**Q.** State and prove Bernoulli’s theorem. What are the limitations of Bernoulli’s theorem? Water is flowing with a speed of 1 m/s in a horizontal pipe with cross-sectional area decreasing from 0.02 m2 to 0.01 m2 at pressure 200 Pascal. Find the pressure at smaller cross-section?
