Like charges repel and unlike charges attract. It will serve as a revision class for everyone and it can be used to revise the formulas in an efficient and guided way. For continuous charge distributions integration methods can be used.
The attached concepts will help the student to understand the chapter and score better marks in the examinations. Electrostatics is a branch of physics that deals with the study of electromagnetic phenomena where electric charges are at rest ie where no moving charges exist after a static equilibrium has been established. For any closed surface S I S E dA 1 0 Q enclosed by S Gauss.
So in this plastic chair and towel game due to the beating of the towel the charges are generated and we get shocked due to these static charges. Electronic Devices and Communication System. Learning the important concepts is very important for every student to get better marks in examinations.

Charges reach their equilibrium positions rapidly because the electric force is extremely strong. To find the magnitude of an electric field from point charge.
Dual Nature of Matter and Radiation Atoms and Nuclei. In physics electrostatics deals with the phenomena and properties of stationary or slow-moving electric charges. Electrostatics the study of electromagnetic phenomena that occur when there are no moving chargesie after a static equilibrium has been established.
Electric Potential Energy in Uniform Fi. Electrostatic- It is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges with no acceleration. Electrostatic phenomena arise from the forces that electric charges exert on each other and are described by Coulombs law.
