What is Gauss’s law class 12?

Gauss Law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux in an area is defined as the electric field multiplied by the area of the surface projected in a plane and perpendicular to the field.

What is electric charge field?

physical property of an object that causes it to be attracted toward or repelled from another charged object; each charged object generates and is influenced by a force called an electric force. electric field. physical phenomenon created by a charge; it “transmits” a force between a two charges.

Is 12th easier than 11th?

Hi 11th standard is comparatively tougher than 12th. so before starting 11th class go through the basics and formulas related to 11th class and try to solve questions of math, physics, chemistry from NCERT book.

How can I study physics in 2 days?

  1. Communication systems.
  2. Atoms and nuclei ( you have done this chapter in chemistry also, around 2-3 topics are different )
  3. Electromagnetic waves.
  4. Dual nature of matter and radiation ( this too you have done in chemistry, around 3-4 topics are more in physics, rest is same )

How can I study physics in 10 days?

  1. Make sure you solve previous year Physics question papers.
  2. You should prepare short notes of important derivations, practice diagrams (device, circuit etc.)
  3. Students are advised to be attentive and careful while solving a question or problem.

Can I skip physics for NEET?

You must not skip preparing for Physics for the NEET exam. In NEET, Physics makes up 25% of the exam. 50% is for Biology, and the other 25% is from Chemistry. So, you must not skip Physics while preparing for the NEET exam.

How can I study for physics in one night?

  1. Make a list of important terms, concepts, and ideas.
  2. Look for summaries in the textbook.
  3. Make more notes as you go.
  4. Make use of mind maps, charts, and graphs.
  5. Teach a friend.
  6. Review your important terms lists.
  7. Study out of order.
  8. Take practice tests.

What is the SI unit of electric flux?

SI Unit of Electric Flux Talking about the unit, the SI base unit of electric flux is volt-metres (V m) which is also equal to newton-metres squared per coulomb (N m2 C-1).

What is the formula of ghost theorem?

Gauss theorem states that the net electric flux through a closed surface is equal to the total or net charge enclosed by the closed surface divided by the permittivity of the medium. If the electric field is present in vacuum then the mathematical equation for the Gauss theorem is ϕ=qenclosedε0 …. (i).

Is Coulomb’s law a universal law Why?

Coulomb’s law is not a universal law. Coulomb’s law is true for point charges and not for charge distributions. As the law works only during certain situations it is not a universal law.
