The graphical method in Linear Programmin is a visual approach used to find the optimal solution of questions in Linear Programming. We have provided NCERT Solutions for Class 12 Linear Programming and we have discussed graphical solutions of all the questions in the exercises for Class 12 Math Linear Programming. The constraints in linear programming are treated as coordinate point and equations are plotted on a graph as straight lines, and the region that satisfies all of them is known as the feasible region. and area outside it is considered Infeasible regions.

Beginner-Level 5
Shiksha's Class 12 Linear Programming, NCERT Solutions provide clear explanation for the concepts of feasible and infeasible regions;
- A feasible region is the common area on a graph that satisfies all the given constraints of a linear programming problem, including non-negativity conditions.
- An infeasible region comprises points that do not satisfy one or more of the problem's constraints. Any point outside the feasible region is considered an infeasible solution.
Students can use NCERT Solutions to understand the concepts for feasible and infeasible reason in the Linear Programming.

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.

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

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

The quantization of charge can be denoted as e = 1.6 * 10? ¹? C. It means that the object's charge is an integral multiple of the elementary charge. Mathematically, it can be represented as q = ±ne, where n is an integer. The charge exists in discrete packets or quanta and is not continuous. For example, a body cannot have a charge of 2.5e but a charge of 3e or -2e. Millikan first observed this quantization of charge in his oil drop experiment. Quantization is consistent with the matter's atomic structure and is a fundamental property of electric charge.

Conductors refer to materials that throughout their structure, allow the free movement of electric charges normally electrons. It happens because of the free electrons present in their outer shells. The examples of conductors include silver, aluminum and copper. On the other hand, there is no free flow of electric charges in the insulators because the electrons are tightly bound to atoms. Examples of the insulators are wood, rubber, and plastic. In electric circuits, the conductors are used as the wiring for the efficient transmission of electricity, and the insulators are used to provide safety by preventing the unwanted flow of curre

The Class 12 chapter 12 Linear Programming carries a weightage of 5 to 6 marks in the Class 12 CBSE Board Exams. Most of the times one long-answer question and some times 2-3 small answer type questions are asked from this chapter. Our NCERT Solutions will help students get full marks through the practice of enough NCERT questions.
