# Worksheet: Static Electricity

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

Q1:

An acetate rod is rubbed with a cloth duster, giving the acetate rod a net positive charge and the duster a net negative charge.

Which object has gained electrons?

• AThe acetate rod
• BThe duster

Which object has lost electrons?

• AThe duster
• BThe acetate rod

Q2:

Two positive charges will each other. Two negative charges will each other. One positive charge and one negative charge will each other.

• Aattract, attract, repel
• Battract, attract, attract
• Cattract, repel, repel
• Drepel, repel, repel
• Erepel, repel, attract

Q3:

What are the two types of electric charge called?

• ALeft charge and right charge
• BPositive charge and negative charge
• CBlue charge and red charge
• DTop charge and bottom charge
• EUp charge and down charge

Q4:

How many types of electric charge are there?

Q5:

The diagram shows two charged particles. Red indicates a positive charge. Blue indicates a negative charge. Will the two particles in the diagram attract or repel each other? • AThe two particles will repel each other.
• BThe two particles will attract each other.

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?

• AGravitational attraction
• BElectrostatic repulsion
• CElectrostatic attraction
• DMagnetic repulsion
• EElectromagnetic repulsion

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(b)
• B(a)

Q10:

The diagram shows two negatively charged ions. Will the two ions attract or repel each other? • AThe two ions will attract each other.
• BThe two ions will repel 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? • ATwo positive charges
• BTwo negative charges
• CEither two positive or two negative charges
• DOne positive charge and one negative charge

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 negative charges
• BTwo positive charges
• COne positive charge and one negative charge
• DEither two positive or two negative charges
