The fundamental relationship between the resulting electric field and electric charge distribution is given by Gauss's law.
It states that the total electric flux (? E) passing through any closed hypothetical surface (called a Gaussian surface) is equal to 1/?0 times the net electric charge (q enc ) enclosed within that surface.
When dealing with charge distributions that possess a high degree of symmetry such as planar, cylindrical, and spherical, Gauss's law significance lies in providing a powerful alternative method to Coulomb's law for calculating electric fields.

The MGU CAT exam is conducted in Thiruvananthapuram, Kottayam, Kochi, Kozhikode, Delhi, Mumbai, Bangalore and Chennai. Candidates have to select the city of preference for test centre allotment in the MGU CAT application form. Candidates must select the test city in which they either live or have easy access to, as once the test city has been confirmed, it will not be changed by the examination authority.

Candidates can use Google Chrome, Mozilla Firefox, Mircosoft Edge or Safari to fill MGU CAT application form. University website is compatible with every web browser. However, it is advised that candidates fill the form on a desktop or a laptop and not on a smartphone browser to minimize chances of error.

A region around a charged object, where another object experiences a force is called an electric field. The formula is - E = F / q? where E is the electric field at a point, q? is the small positive test charge placed at that point, and F is the force experienced by q?
The electric field is a vector quantity that has both magnitude and direction. The electric fields are visually represented by the electric field lines. The electric field starts with positive charges and ends with negative charges. The field's strength is indicated by the density of the field lines. The electric fields can be measured in V/m (volts per meter) and N/C (n

Yes, candidates can apply for multiple courses in MGU CAT if they need the eligibility criteria for those courses. The MGU CAT question paper for each course will have course specific questions and one needs to clear the test to be eligible for admission. Thus, candidates must first make sure they can clear the test for multiple courses only then should they apply. Otherwise, they should apply to their most preferred course only.

There is no provision to edit MGU CAT application form after submission. Candidates can edit their forms till the time they haven't submitted it. Once submitted the form will not be available for editing. Thus, candidates must fill the MGU CAT application form with correct details in the first attempt only. If they make any error, they will have to fill a fresh form and pay the fee again.

The MGU CAT application fee is not refundable. Thus, candidates make sure they do not make any error in the form and that they have fill another form. Even if they have filled the form correctly, but choose to not appear in the exam, the fee amount will not be refunded.

According to Shiksha's electric charges and fields class 12 notes, Coulomb's law states that if there are two stationary point charges, the electrostatic force between them is inversely proportional to the square of the distance between them and directly proportional to the product of the charges.
Mathematically,
F = (1 / 4? ) * (q? / r²)
Here r is the distance between the charges, q? and q? are charges and? is the permittivity of free space. Coulomb's law assumes charges are at rest and it is valid for point charges in vacuum or air. When the medium is not a vacuum and the charges are moving, the limitations include inaccuracy. This la
