Electrostatics Quiz

The total charge on a body is the algebraic sum of all charges present on the body. It can be calculated using the formula $Q = q_1 + q_2 + ... + q_n$ where $Q$ is the total charge and $q_1, q_2, ..., q_n$ are the individual charges on the body.

Quantization of charge refers to the fact that the charge on a body is the integral multiple of the charge on a single electron. It can be represented as $Q = ne$, where $e$ is the charge on a single electron and $n$ is an integer. For example, the charge on a body can be 1C, which corresponds to $n = 6.25 × 10^{18}$ electrons.

Charge is an intrinsic property of matter due to which it experiences electrostatic forces of attraction and repulsion. It can be positive (e.g. proton) or negative (e.g. electron). The properties of charge include attraction and repulsion between like and unlike charges, the additive nature of charge, and the quantization of charge.

There are two types of charges: positive (e.g. proton) and negative (e.g. electron). Positive and negative charges experience electrostatic forces of attraction and repulsion. Like charges repel each other, and unlike charges attract each other.

The number of electrons in 1C charge can be calculated using the formula $q = ne$, where $q = 1C$ and $e = 1.6 × 10^{-19}C$. Therefore, $n = \rac{q},{e} = \rac{1},{1.6 × 10^{-19}} = 6.25 × 10^{18}$ electrons.
