Test Bank Solution Manual for Electricity and Magnetism (Latest Update 20224-2025)
How does increasing the distance between charged objects affect the electric force between them? -
Answers The electric force decreases because the distance has an indirect relationship to the force.
Two balls are placed near one another and hang down, as shown below.
Which conclusion is supported by this evidence? - Answers Neither ball has a charge.
As Chelsea removes her clothes from the dryer, she sees sparks, which are examples of . - Answers static
discharge
The area around a charged object where the object can exert a force on other charged objects is an
electric . - Answers field
An electroscope is a device that detects charge on objects that touch it or are brought near it. John rubs
a piece of cotton fabric on a plastic rod and then touches the rod to the electroscope.
What methods of charging does John use? - Answers John charges the rod through friction, then charges
the electroscope through conduction
Which change increases the electric force between objects? - Answers Electrons are added to two
negatively charged objects.
Alfredo makes a diagram to organize his notes about charging objects.
Which statement should he place in the region marked X? - Answers The objects have the same charge.
The diagram shows two charged objects, X and Y.
Based on the field lines, what are the charges of the objects? - Answers X: positive
Y: positive
A positively charged object will attract an object that has . - Answers negative charge
Tisa makes a diagram to organize her notes about charging objects.
, Which statement should she place in the region marked X? - Answers Electrons move between objects.
Hiro rubs an inflated balloon on his hair, and his hair sticks to the balloon. As he moves the balloon away
from his head, how does the electric force change? - Answers The electric force decreases because the
distance increases.
How does increasing the amount of charge on an object affect the electric force it exerts on another
charged object? - Answers The electric force increases because the amount of charge has a direct
relationship to the force.
For which pair of objects would adding the same amount of electrons to each object result in a decrease
in the electric force? - Answers two positively charged objects
Which factors affect the strength of the electric force between two objects? - Answers the distance
between the objects and the amount of charge on the objects
Measurements of two electric currents are shown in the chart.
Which best compares the two currents? - Answers Current Y has a greater potential difference, and the
charges flow at a slower rate.
The chart shows the voltage of four electric currents.
Which is best supported by the data in the chart? - Answers Current X has a lower potential difference
than Current Y.
Nina is working with electricity and shortens the wires through which the current is flowing. What is
Nina most likely trying to accomplish? - Answers decrease resistance
Electric current flows through paths called circuits. People often build circuits using wires, resistors, and
batteries. A battery is a voltage source.
A circuit with which components has a current with the greatest voltage? - Answers wires, a 9V battery,
no resistors
Which two wire properties would provide the greatest resistance to the flow of a current? - Answers
long, thin
In the diagram, the arrow shows the movement of electric charges through a wire connected to a
battery.
How does increasing the distance between charged objects affect the electric force between them? -
Answers The electric force decreases because the distance has an indirect relationship to the force.
