That's only the force between those two charges. The F in the diagram is the net force on the -1nC charge from the other two.Lilian Chan said:
In science, charges refer to the fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of charges: positive and negative.
Charges interact with each other through the electromagnetic force. Like charges repel each other, while opposite charges attract each other.
The unit of charge in the International System of Units (SI) is the coulomb (C). One coulomb is equal to the charge of 6.24 x 10^18 electrons.
Charges can be measured using an instrument called an electrometer, which measures the force between two charges. The amount of force is directly proportional to the magnitude of the charges.
Trigonometric functions are mathematical functions that relate the angles of a triangle to the lengths of its sides. Some common trigonometric functions include sine, cosine, and tangent.
