Why charge is positive or negative?
There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
Why is it called a negative charge?
In metals, like in household electrical wire, the charge carriers are indeed just electrons. Serway, Franklin identified electric charge carriers after a series of rubbing experiments. Without much knowledge of the underlying physics, he simply made a choice that made sense to him by calling electrons negative.
What is earthquake Class 8?
Earthquakes: Are earthquake is a sudden shaking or trembling of the earth which lasts for a very short time. Earthquakes can cause immense damage to buildings, dams, etc. They may also cause floods, land slides, tsunamis and loss of life. It is caused by a disturbance deep inside the earth’s crust.

What is the difference between small Q and Capital Q in physics?
Big Q represents the source charge which creates the electric field. Little q represents the test charge which is used to measure the strength of the electric field at a given location surrounding the source charge.
