NCERT class 12 Physics exemplar NCERT class 12 Physics exemplar comprise of questions taken from ncert exemplar class 12 physics book along with questions from previous year question papers and sample papers from different sources.

Physics problems and solutions for class 12 pdf are provided here which are similar to the questions being asked in previous year board as well as competitive examinations. It is very important for the students to study exemplary questions as they give them feedback on their preparation level and thereby help them to reassess their reading strategy in order to pass board and entrance examination with flying colours.

NCERT Exemplar Problems Class 12 Physics – Electric Charges and Fields

When matter experiences a force when placed in a magnetic field, the property of matter is called Electric charge. The field surrounding an electric charge is called an electromagnetic field, where opposite charges attract each other. It is a scalar quantity and the charge can be either positive or negative in nature. Electric charges are measured in coulombs and it can be quantized in nature.
