Description
Electrostatics, the study of charges in motion, is a very important branch of Physics that has proven very useful as the knowledge of this topic has led to the development of inkjet printers, laser printers, photocopiers, and even electrostatic air filters. In this quiz, we will be seeing some laws concerning electrostatics formulated by great Physicists like Coulomb and Gauss.
Electrostatics is the study of electric fields in static equilibrium. The study of electromagnetic phenomena that occurs when charges are in motion is also called electrostatics. As seen in quiz one, force is simply the attraction or repulsion between charges of opposite signs and is defined by Coulomb’s law of electrostatics which you will see along the way. But this force varies with 2 factors, the number of charges and the distance separating the charges. The higher the charges the larger the force and the longer the distance separating the charges, the smaller the force.
We know this is still just a summary of this broad topic. You will find more interesting things along the way which you will learn. You will find more quizzes on other subjects here. Take the quiz and see how well you are familiar with electrostatics.
Best of Luck
