How does static electricity happen? provide 3 real life examples of electro static electricity.

Explanation:

When two materials come in contact with each other , there occurs the movement of electrons from one material to other , hence , there is an excess positive charge on one of the material , and hence lead to static electricity .

Examples -

brushing dry hairs via a plastic comb can generate static electricity .Clothes stuck to one another in the dryer Walking on the floor with carpet and touching a door can lead to a shock , due to static electricity .

F=8.87 N

Explanation:

Coulomb's Law

The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.

Written as a formula:

Where:

q1, q2 = the objects' charge in coulomb

d= The distance between the objects  in meters

Object 1 has a charge of

Object 2 has a charge of

They are separated by a distance of

d = 0.099 m

Calculate the force:

F=8.87 N
