Question 1

Two spheres are charged with the same charge. What will happen to the charge if the spheres are connected with a conducting wire the radii of the spheres are different?

Question 2

The potential of a capacitor is doubled from V to 2V .it is further doubled from 2V to 4V. Then what will be the difference in the work done.

Question 3

A fully charged capacitor is disconnected from the battery. Then a dielectric slab is inserted between it. Which of the statement is true

Question 4

What happens to capacitance, charge, and voltage if a dielectric material is placed between the plates a parallel-plate capacitor which is connected with constant voltage?

Question 5

The circuit is shown consists of an air-spaced parallel plate capacitor in series with an A.C. supply and a lamp bulb, the filament of which glows with a certain brightness. A sheet of glass is inserted between the plates of the capacitor. Then, which of the following quantities decreases?

Question 6

Two identical conducting spheres carry identical charges. If the spheres are set at a certain distance apart, they repel each other with a force . A third conducting sphere, identical to the other two, but initially uncharged, is then touched to one sphere, and then to the other before being removed. The force between the original two spheres is now

Question 7

What will be the potential of a conducting cylinder if some charge is given to its surface?

Question 8

A point charge is placed at the centre of a metallic shell which carries a charge on it. Another charge is placed outside the shell. If all charges are positive, then what will be the net force on?
