Introduction to Electrostatics
Electrostatics is the branch of physics that deals with
stationary charges and their interactions. It is an important
area of study as understanding stationary charges is crucial
in a variety of fields, including engineering, chemistry, and
physics. Moreover, the principles of electrostatics help to
explain various everyday phenomena, such as how electric
charge builds up on an object when it is rubbed against
another (friction) or how lightning works.
Electric Charge and its Properties
Electric charge is a fundamental property of matter that
can exist in two forms: positive and negative. An object is
said to be positively charged when it has a surplus of
protons (positive charges) and negatively charged when it
has a deficit of protons or an excess of electrons (negative
charges). An object with no net charge is said to be neutral.
Types of Bodies
Bodies can be classified as:
1. Neutral bodies: These are objects or systems with no net charge, i.e.,
the number of positive charges equals the number of negative charges.
1. Positively charged bodies: These are objects or systems with a net
positive charge, i.e., the number of positive charges is greater than the
number of negative charges.
Negatively charged bodies: These are objects or systems with a net
negative charge, i.e., the number of negative charges is greater than the
number of positive charges.
Charging Techniques
Charging techniques involve transferring charges between
objects to create an electric charge or changing an object's
charge without any physical contact. The three main
charging techniques are:
2. Conduction: This involves charging by physical contact, where electrons
are transferred from one object to another. For example, touching a
neutral or positively charged object with a negatively charged object
results in the transfer of electrons.
2. Induction: This involves charging without physical contact. When a
charged object is brought close to a neutral object, it changes the
distribution of charges in the neutral object without any actual transfer of
electrons. Once the charged object is removed, the neutral object can
retain its acquired charge.
2. Friction: This involves rubbing two objects together, which results in a
