A force exerted by magnets when they attract or repel each other is called______________.
Coulomb's Law
Electric Charge
Magnetism
Electrostatic
What is caused by the motion of electric charges?

Coulomb’s Law states that
opposite charges repel while alike charges attract
the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges
the force of attraction or repulsion between two charged bodies is indirectly proportional to the product of their charges
The force is equal to the charge on 6.24 x 10^18 protons

Conduction
Materials that does not allow electrons to flow freely is called _____________.
Conduction
Conductors
Insulators
dry wood and sea water
Why does electric wires have rubber coating?
To prevent electricity from flowing directly to our hands leading to electric shock
To allow electricity in flowing directly to our hands leading to electric shock
Rubber provides conduction covering the wire
Rubber is a good conductor of heat and light and it is nonresponsive towards heat and light
The following materials are good conductors of electricity except

neutral
neutron
no charge
charged
A positively charged object has _____________________________.
more positive charges than negative charges
more negative charges than positive charges
positive charges only
two negatively charged objects
Which of the following statement is incorrect?
A negatively charged object has lesser negative charges than positive charges
When one object or material rubs over another, electrons are often transferred from one to the other
if electrons are rubbed off, then the object or material will have a positive charge
As charges (electrons) build up, there is always a tendency for them to return to their original locations. All that is needed is a pathway for charges to use
