1. There are 7 electrons
2. The charge of stick is negative & the wool is
positive
3. Because its electric field is very small and charges
act only within their electric field.
4. Yes, because the objects involve gained and gave
electron. One thing more the charges did not move
in a connection, so it is static electricity.
Explain how an object
becomes positively charged
or negatively charged.
1. Relate organizational structure of
matter with emphasis on charges.
2. Infer interactive behavior of charges.
3. Define or illustrate electric field.
4. Describe the processes and products of
electrostatic charging.

ELECTROSCOPE is a device that detects and
measures an electric charge, usually consisting of
a rod holding two strips of gold foil that separate
when the same charge is applied to each
8.
Upon completing thismission, you can readily
explain the basic rule about electric charges.
Also the behavior of electric charges.
Our story today evolves from CHARGES. The
big questions are: “how do charges behave?”
and “where a positive charge or negative
charge likes to stay with? Let’s see,

STATIC ELECTRICITY iscreated when an object gives
up or gains electrons. Rubbing wool over something
made of plastic or hard rubber gives that object a
negative charge which will attract any object with
a positive charge. The wool gives up electrons to
the plastic. This kind of charge is called
"static" because it is not moving along a wire or
other conductor.
Once upon a time, the two
neutral charge friends are
scheduled for rubbing.
