A level Electrostatics Quiz 1

16 Questions

Quiz 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. From this, we can see that Studying electrostatics could even land you a very good job in the field of computer engineering. This quiz will contain 15 questions, each having four options for a correct answer. Students will therefore not only be tested but will be tested in a tricky manner, so taking the quiz will help avoid that during exams.

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. When two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, these objects acquire equal and opposite charges and an attractive force develops between them, this phenomenon is known as static electrostatics. The object that loses electrons usually becomes positively charged, and the other becomes negatively charged. The force is simply the attraction between charges of opposite signs and is defined by Coulomb’s law of electrostatics which you will see along the way. 

This is 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.
