Question

What is the nature of electric charge?
A) Only positive
B) Only negative
C) Positive and negative both
D) Neutral

Answer 1

Hint: When we rubbed the substance Amber with the wool, it started attracting light weight things as paper, straw etc. This property is called attraction. This property of attraction in this type of substance is due to the electricity. When any substance is electrified, it is called charged. And can be charged negative or positive.

Complete step by step answer:
Electric charge is the physical property of an issue that makes it experience a power when put in an electromagnetic field. There are two kinds of electric charge: positive and negative (regularly conveyed by protons and electrons individually). Like charges repulse one another and dissimilar to charges pull in one another. An item with a nonappearance of net charge is alluded to as neutral.
Electric charge is a rationed property. the net charge of a separated framework, the measure of positive charge short the measure of negative charge, can't change. Electric charge is conveyed by subatomic particles. In customary issues, negative charge is conveyed by electrons, and positive charge is conveyed by the protons in the cores of particles. In the event that there are a bigger number of electrons than protons in a bit of an issue, it will have a negative charge, if there are less it will have a positive charge, and if there are equivalent numbers it will be neutral.

Hence option C is correct.

Note:
Electric field depends on the amount of charge. The larger the amount of charge, the larger the electric field is formed. Electric field lines are always coming out from positive charge and go to infinity. And in the negative charge electric field lines come from infinity and enter in negative charge.
