## NCERT Exemplar Solutions for CBSE Class 12 Physics

MTG provides student-centered educational approaches and support. It does this by producing and publishing relevant, exam appropriate course materials and workbooks which enable students to self-pace, self-study and self-evaluate their knowledge and grasp over their course matter and syllabus. This real-life scenario allows students to see for themselves what their actual achievement level is, where more effort is required and how the student ranks against cohorts ahead of exams. Apart from publishing the exam centric books, MTG is also engaged as the white labelled course material provider to thousands of coaching institute. We customize the material as per the need of the client and do every possible effort to satisfy them.

Students are advised to solve these questions when they have completed a particular topic. These Solutions are prepared in such a way that students can concentrate on building the basic support as well as in education building and helps students to have a better knowledge of the topics.
how to think on your feet under pressure

Class 12 itself endows an extreme pressure on a child as it requires a student to be extra meritorious in board exam as well as towards his career goal. NCERT books have been prescribed by Central Board of Secondary education and cover each and every topic in detail as desired by the board. Moving ahead what next?

The improvement of the website and its contents are based on your suggestion and feedback. NCERT exemplar questions are very good in concept developing and revision. These questions also gives excellent practice for JEE — Mains exam as well as the other competitive examination. After completing the syllabus of — 19 , students are advise to to these questions. Quantization of Electric Charge: The magnitude of all charges found in nature are in integral multiple of a fundamental charge. Equipotential Surface: A surface on which electric potential is equal at all the points is called an equipotential surface.
