1.Explain what happens when we ground any shell and if one surface is charged. Please tell all the variations possible regarding this.
2.How does dynamo work on the basis of electromagnetic induction. Give examples and explain that how do i understand that the particular equation follows lepton law
3. A particle is dropped from a height h. A constant horizontal velocity w is given to the particle. Taking g to be constant everywhere kinetic energy e of the particle with respect to time t is correctly shown? Why the graph is so and tell why not other graphs possible
4. In a projectile motion kinetic energy varies with time as per the standard graph and why not any other type of graph is possible?
