(N/A) Any matter is primarily composed of two particles: $Electron$ and $Proton$.
The charge on an $Electron$ is considered negative, and the charge on a $Proton$ is considered positive. Electric charge is a scalar quantity.
When two non-conductors are rubbed together, electrons are transferred from one body to another due to their lower mass compared to protons. The body that gains electrons becomes negatively charged, and the body that loses electrons becomes positively charged.
The terms 'positive' and 'negative' for electric charges were introduced by the American scientist $Benjamin$ $Franklin$.
$A$ body possessing a net charge is called a charged body, while a body with no net charge is called a neutral body.
When two bodies with equal and opposite charges are brought into contact, they neutralize each other.
The following table shows the types of charges acquired by various non-conducting objects when rubbed together:
| $1. \text{Pair}$ | $2. \text{Positive Charge Object}$ | $3. \text{Negative Charge Object}$ |
| Glass rod and Silk cloth | Glass rod | Silk cloth |
| Wool and Plastic comb | Wool | Plastic comb |
| Cat fur and Ebonite rod | Cat fur | Ebonite rod |
