Physics notes for class 12-Electrostatic charges

We offer one in every of the best 12th Physics course to our students so they'll simply score sensible marks within the board exams. Keeping seeable the most recent pattern of question paper of the CBSE board exams, we've got developed the Physics study material & CBSE sample papers consequently by our greatest teacher. be a part of US today…!
In this article, ‘Electrostatic Charges’ from Class 12 Physics is being discussed.
Physics notes for class 12 - Electrostatics: Electrostatics is that the branch of Physics that deals with the study of charges at rest.
Electric charge:
Electric charge is something possessed by material objects that make it possible for them to exert electrical force and to respond to electrical force. SI unit of charge is Coulomb (C).
What is frictional electricity?
The charge obtained by a body on rubbing with another body is named resistance electricity.

Example: once a glass rod is rubbed with silk, the glass rod gets charged and silk   gets charged.
How will a body get charged?

A body gets charged by the transfer of electrons. The body that loses electrons gets charged and also the body that gains electrons gets charged.

Thus, there square measure 2 varieties of charges: electric charge and charge.

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton  (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled.
