7 Questions

1. A charge is distributed along an infinite curved line in space with linear charge distribution λ. What will be the amount of force on a point charge q kept at a certain distance from the line?
2. How many electrons must be added to an isolated spherical conductor of radius 20cm to produce an electric field 1000N/C just outside the surface?
3. What is the charge density of the conducting plate shown below if a total charge of 10C is applied to it? Consider the bigger circle as a solid part and a smaller circle as a hollow part.
4. What is the dimension of linear charge density?
5. The term ‘volume charge density’ is valid for a solid conducting sphere.
6. A circular annulus of inner radius r and outer radius R has a uniform charge density a. What will be the total charge on the annulus?
7. A solid non conducting sphere of radius 1m carries a total charge of 10 C which is uniformly distributed throughout the sphere. Determine the charge density of the sphere.
