The concept of unit charge can be cleared easily from equation 1.3. Lets suppose r=1m, q1=q2=q and the force F=9 X 10 9. By substititing the values in equation 3 we get: Or So, S.I. unit of charge is Coulomb. Conclusion: When two charges of 1 coulomb each ...

The term conservation of electric charges means that charges can neither be created nor destroyed in separation. In simple words, charges can be created or destroyed only in same and opposite pairs. When two bodies are rubbed together then one gets negative and other gets positive ...

The whole amount of charge on a body is the algebraic sum of total no of charges scattered anywhere on the body. Be careful while taking the algebraic sum, the sign of the charges must be taken. E.g. When +2q and +q charges on a ...

It is the property by which any charge lives only in separate collection or bundle of specific minimum charge. Positive and negative charge in the equation is denoted by q. The equation is shown below: q=ne n can have both negative as well as positive values. ...

Nucleus is present in the center of Atom. It contains protons and neutrons. Protons carry positive charge and neutrons carry negative charge. The protons and neutrons in an atom are equal. So atom as a whole is neutral. Around the nucleus, there are negatively charged ...

Electric charge is the feature of the sub atomic particles which determines the electromagnetic interaction between them. ...

The study of electric charges at rest is called electrostatics. Its other name is ‘static electricity’. A Greek philosopher ‘Thales’ in 600 BC conducted an experiment. He observed that when amber was rubbed with some woolen cloth it gets charged and immediately started attracting small ...

• The stars having zero magnitude will be less bright than the stars having negative magnitudes. • Those stars which are red in color will have less temperature than the stars having blue color. • The galaxy count of our universe is 1011 • The weight of Milky Way galaxy is ...
