So electric charge and field is not the term we used to hear in our daily life but if your are a class 12th science student just like me then you are familiar with these terms. Torque on an electric dipole placed in a uniform electric field (E) is given by that electric force is also as pervasive and is in fact stronger than the gravitational force by several orders of magnitude (refer to Chapter 1 of Class XI Physics Textbook). Electric Dipole Moment The strength of an electric dipole is measured by a vector quantity known as electric dipole moment (p) which is the product of the charge (q) and separation between the charges (2l). SI unit of electric field is N/C (Force/Charge). (a) electrostatic unit, esu of charge or stat-coulomb (stat-C) CBSE Class 12 Physics Notes Chapter 1 Electric Charges and Fields discusses these facts in detail.Electrostatics deals with the study of forces, fields and potentials arising from static charges. 25.
