Students who want to get the 2nd Year Physics Chapter 12 MCQs With Answers Electrostatics are here in the right place. Electrostatics is the study of charges at rest under the action of electric forces. In this chapter, it is important to study Coulomb’s law, Electric field lines and then there are applications to electrostatics. Then the concept of Electric Flux is important which is the number of lines of forces passing through the element that is placed in an electric field. Electrostatics also finds its way into Gauss’s law which has some very useful applications. Next, the concept of Electric Potential and Electron Volt is important. We can also find the charge on an electron through Millikan’s Method. Then, in the end, there is the concept of the capacitor. Now, let’s have a look at the important MCQs of this chapter to prepare for the entrance test.
