Attraction & repulsion of atom:
It can be observed, that if two negatively charged bodies are brought together, there is a force of repulsion between them. Similarly if two positively charged bodies are brought together there is a force of repulsion. However, if a positively charged body is brought close to a negatively charged body, they attract each other. Hence:
Like Charges Repel, Unlike Charges Attract.
The force of attraction or repulsion is governed by an inverse square lawUNIT OF CHARGE
The charge on an electron is very small, therefore a more practical unit of charge called a Coulomb, has been chosen:
One Coulomb = 6.29 x 1018 electrons

Vectors Representing Forces A force can be represented by a vector (drawn as an arrow). The arrow's length is related to the size of the force and the arrow's direction shows y

What is the relationship among the period and the square root of the length? The graph is linear, so the period is proportional to the square root of the length of the string.
