COMMON QUESTIONS
1. State and prove conservation of linear momentum.
2. Define potential gradient. Establish a relationship between potential gradient and electric field intensity.
3. What is lateral shift? Derive an expression for it.
4. Define angle of friction and angle of repose and develop their relation.
5. State the principle of conservation of energy. Show that total mechanical energy of a body is conserved when it moves under the action of gravitational field.
6. Derive the equation of state for an ideal gas.
INDIVIDUAL QUESTIONS
1. A carpet is beaten with a stick to remove the dust particles. Why?
2. Explain, why a cricketer moves his hands backwards when holding a catch?
3. How the K.E. of an object change if its momentum is doubled?
4. No energy is consumed in planetary motion, why?
5. Which has more molecules, a kilogram of hydrogen or a kilogram of oxygen?
6. Why does the cycle tube burst some times in summer?
7. Write the unit of the universal gas constant and give it’s physical meaning.
8. Why does diamond sparkle?
9. What do you mean by equipotential surfaces?
10. Why does a clear pool of water always appear to be shallower than it actually is?
11. A man inside an insulated metallic cage does not receive shock when the cage is highly charged. Explain.
12. Electric field intensity in a given region is zero. Can we conclude that electric potential must be zero?
