# Worksheet: Static Electricity

In this worksheet, we will practice describing the forces experienced by electrically charged particles and objects.

**Q2: **

- Aattract, attract, attract
- Battract, repel, repel
- Crepel, repel, repel
- Dattract, attract, repel
- Erepel, repel, attract

**Q3: **

What are the two types of electric charge called?

- ABlue charge and red charge
- BPositive charge and negative charge
- CLeft charge and right charge
- DUp charge and down charge
- ETop charge and bottom charge

**Q4: **

How many types of electric charge are there?

**Q6: **

A polythene rod is rubbed with a cloth duster, giving it a net negative charge. A second polythene rod is rubbed with a duster and the two rods are brought close together. What will happen?

- AThe two polythene rods will repel each other.
- BThe two polythene rods will attract each other.

**Q7: **

The buildup of what type of particle gives an object an electric charge?

- AA proton
- BAn electron
- CA neutron

**Q8: **

Two positively charged particles exert a repulsive force on each other that increases as they are brought nearer to each other. What is the name given to this force?

- AElectromagnetic repulsion
- BMagnetic repulsion
- CElectrostatic attraction
- DElectrostatic repulsion
- EGravitational attraction

**Q9: **

The diagram shows two pairs of negatively charged particles. The particles in the first pair (a) are closer together than the particles in the second pair (b). For which pair of particles will the repulsive force between them be greater? All four charges are equal. The two pairs of particles are in separate locations, far away from each other.

- A(a)
- B(b)

**Q10: **

The diagram shows two negatively charged ions. Will the two ions attract or repel each other?

- AThe two ions will repel each other.
- BThe two ions will attract each other.

**Q11: **

The graph shows the force experienced by two charged particles against how far apart they are. If negative values on this graph represent an attractive force, what are the charges of the two particles?

- AEither two positive or two negative charges
- BTwo negative charges
- COne positive charge and one negative charge
- DTwo positive charges

**Q12: **

The graph shows the force experienced by two charged particles against how far apart they are. If positive values on this graph represent a repulsive force, what are the charges of the two particles?

- ATwo positive charges
- BEither two positive or two negative charges
- COne positive charge and one negative charge
- DTwo negative charges
