Electrostatics | Digital Notes

- Branch of physics which deals with properties of charge at rest.

1-scalor quantity

2-It is of the types --> (-ve):proton - 1.6 * 10(-19)[\,(+ve) 9.1*10(-19)

3(-ve) charge: abundance of e-[electron](excess of electron)

4charge is quantized.(can take only specefic value)

Q = ne (1.6*10[-19])(n = number of electrons)

5.Charge does not depend on velocity.

6.Net charge can nither be created nor destroyed.

7.CHARGE AT REST CAN CREATE ELECTRIC EFFECT ONLY AND CAN EXPERIENCE ELECTRIC FORCE ONLY.

8.CHARGE MOVING WITH CONSTANT VELOCITY WILL CREATE ELECTRIC AS WELL AS MAGNETIC EFFECTS AND IT CAN EXPERIENCE ELECTRIC AS WELL AS MAGNETIC FORCES.

8.CHARGE MOVING WITH VARIABLE VELOCITY WILL EMMIT ELECTRO MAGNETIC RADIATION.

E0(epsilon) = 8.858*10(-12)C2/N-m2
