IIT JEE Exam Electrostatics Study Material

Electrostatics is a vital branch of Physics. It is an interesting branch and questions are often asked from it in the JEE. It is important to have a strong grip on the topics of electrostatics in order to remain competitive in the JEE.

Introduction

The Greek word for amber is “elektron”; this is the origin of the terms electricity and electron. Electrostatic is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges with no acceleration.

While it’s hard to see the electric charges that are responsible for electricity, it’s easy to see their effects. They’re all around us: in the sparks and shocks of a cold winter day, the imaging process of a xerographic copier, and the illumination of a flashlight when you turn on its switch. Although we often take electricity for granted, it clearly underlies many aspects of our modern world.

Just imagine what life would be like if there were no electric charges and no electricity. For starters, we’d probably be sitting around campfires at night, trying to think of things to do without television, cell phones, or computer games. But before you remark on just how peaceful such a pre-electronic-age existence would be, let me add one more sobering thought: we wouldn’t exist either. Whether it’s motionless as static charge or moving as electric current, electricity really does make the world go ‘round.

Electricity may be difficult to see, but you can easily observe its effects. How often have you found socks clinging to a shirt as you remove them from a hot dryer or struggled to throw away a piece of plastic packaging that just won’t leave your hand or stay in the trash can? The forces behind these familiar effects are electric in nature and stem from what we commonly call “static electricity.” Static electricity does more than just push things around, however, as you’ve probably noticed while reaching for a doorknob or a friend’s hand on a cold, dry day. In this section, we’ll examine static electricity and the physics behind its intriguing forces and often painful shocks.

When a plastic comb is rubbed with your hairs, it acquires the property of attracting light objects such as paper pieces.
