NCERT Solutions for Class 12 Physics Chapter 1 Electric Charges And Fields

The electric field is an alteration of space caused by the presence of an electric charge. The electric field mediates the electric force between a source charge and a test charge. The field is a vector; by definition, it points away from positive charges and toward negative charges. In chapter Electric Charges and Fields, we will be solving questions on how to calculate forces between two charged particles, which are kept at a certain distance from each other. We will be explaining the reason behind the charge appearing in materials due to rubbing against each other just like when you rub a glass rod with a silk cloth.
