Question

What does electric charge mean?

Answer 1

Electric charge, the basic property of matter carried by some elementary particles that govern how the particles are affected by an electric or magnetic field.
Electric charge, they can be positive or negative, occurs in discrete natural units and is neither created nor destroyed.
Electrons have a"negative" charge, and protons have what we call a "positive" charge.

Complete step-by-step solution:
What do "negative" and "positive" mean here? It refers to these 2 particles having the opposite types of charges. Generally, The negatively charged particles attract the positively charged particles and vice versa.
What does "attract" mean here? It means that when we bring a proton and an electron close, they will pull each other towards themselves, and thus fall into each other.
that is specified by the equation,
$F = k\dfrac{{{q_1}{q_2}}}{{{d^2}}}$
where ${q_1}$ refers that the amount of charge in one of them we can say, the electron
${q_2}$ refers that the amount of charge in the other we can say, the proton
$d$ refers that the distance between the two in space, and
$k$ is a coulomb constant
There are two types of electric charge:
Positive commonly carried by protons
Negative commonly carried by electrons
Like charges repel each other and unlike charges attract each other.
An object which has no net charge is referred to as neutral

Note: The interactions between particles we observe in nature can be described in terms of four fundamental types of force or interaction: gravitation, electromagnetism, weak interaction, and strong interaction.
They're distinguished by their qualitative properties.
Attraction and repulsion of charges are the cause of force such that Coulomb force or electrostatic force.
