Electrostatics

Front

When an object gains electrons it becomes __________

Back

Negatively charged

Front

An atom of oxygen has 8 protons and 10 electrons, this means the atom is ____________

Back

negatively charged because it has excess electrons

Front

After a balloon is rubbed against wool, the two objects will ________ each other because they have ___________ charges.

Back

attract, opposite

Front

Which statement is true of a positively charged object?

Back

There is a lack of electrons on a positively charged object.

Front

How do you determine which object acquires transferred electrons when two objects are rubbed together?

Back

Transfer is based on how much electron affinity that each object has.

Front

What is the end result of charging by contact?

Back

Both objects have the same charge, so they will repel one another.

Front

What method of static charging is shown in this picture?

Back

Friction

Front

Which image shows a neutral conductive pith ball after a positively charged balloon is brought near the left side, but doesn't touch? Options: A, B, C, D

Back

D

Front

How do you determine which object acquires transferred electrons when a charged object contacts another object?

Back

Always transfer from the more negative to the more positive object

Front

Which electrostatics phenomena is shown in this picture?

Back
