Q & A

What is the purpose of the guess paper in this video?

The purpose of the guess paper is to provide students with predicted questions and topics that are likely to appear in the upcoming Class 12th Physics exam under JKBOSE for 2025. The teacher, Salim Sir, assures that focusing on these questions will help students score above 80 marks.

How many marks can students expect if they study only the key questions mentioned in the guess paper?

If students focus solely on the key questions provided in the guess paper, they are guaranteed to score at least 70–80 marks in the exam. In fact, the teacher claims that these questions alone could result in scores as high as 85-90 marks.

What are some of the key topics covered in the 'Electrostatics' section of the guess paper?

The key topics covered in the 'Electrostatics' section include Coulomb's Law in vector form, Electric field intensity on axial and equatorial lines, Torque on a system of charges, Potential energy of charge systems, and Gauss’s Law. The teacher emphasizes understanding each question thoroughly.

What is the expected format for numerical problems in the 'Current Electricity' section?

In the 'Current Electricity' section, numerical problems may involve calculating drift velocity, understanding Ohm’s Law (in its microscopic form), applying Kirchhoff’s Laws to circuits, and determining internal resistance and EMF of a cell. The teacher highlights that these topics are essential for scoring well in this section.

What does the teacher say about the importance of 'Optics' in the exam?

The teacher mentions that 'Optics' is one of the largest chapters in terms of marks. Key topics include the astronomical telescope, refraction on concave and convex spherical surfaces, the lens maker's formula, and Huygens’ Principle. The teacher also emphasizes the importance of numerical questions related to refractive index and mirrors/lenses.

What should students focus on in the 'Magnetic Effects of Current' section?

In the 'Magnetic Effects of Current' section, students should focus on understanding the Biot-Savart Law, Ampere’s Circuital Law, and calculating the magnetic field at the center of a current-carrying loop. Additionally, topics like torque on a rectangular loop and the moving coil galvanometer are important.

Which conceptual topics are mentioned as important in the 'Modern Physics' section?

In the 'Modern Physics' section, the teacher highlights De Broglie's relation, Einstein’s Photoelectric equation, the characteristics of photons, and the properties of semiconductors (n-type and p-type). Students are also advised to understand the forward and reverse biasing of diodes and the energy band diagrams.

What is the significance of the 'Nuclear Physics' section in the guess paper?

The 'Nuclear Physics' section includes important topics like Bohr’s model (orbit radius), Rutherford’s scattering, and binding energy of nuclei. The teacher advises students to be prepared for both theoretical and numerical questions related to these concepts, such as calculating energy from mass defect.

Why is the teacher confident that following this guess paper will lead to high marks?

The teacher is confident that focusing on the key questions and topics provided in the guess paper will lead to high marks because, based on previous experience, these topics are most likely to appear in the exam. The teacher has a track record of accurately predicting exam questions.

What additional guidance does the teacher offer to students for exam preparation?

The teacher suggests that students not only cover the provided topics but also practice numerical problems and ensure conceptual clarity. Additionally, the teacher encourages students to attend live sessions where more detailed explanations and additional practice problems will be shared.
