A small, positively charged ball is moved close to a large, positively charged ball. Which describes how the small ball likely responds when it is released?

It will move toward the large ball because like charges repel.
It will move toward the large ball because like charges attract.
It will move away from the large ball because like charges repel.
It will move away from the large ball because like charges attract.

It's a TEST give me at least 80-90 to pass it.

The correct answer is: It will move away from the large ball because like charges repel.
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?

The electric force increases because the balloon loses its charge.
The electric force increases because the distance increases.
The electric force decreases because the distance increases.
The electric force decreases because his hair loses its charge.
The correct answer is: The electric force decreases because the distance increases.
Which factors affect the strength of the electric force between two objects?

the mass of the objects and the distance between the objects
the amount of charge on the objects and the type of charge on the objects
the distance between the objects and the amount of charge on the objects
the mass of the objects and the amount of charge on the objects
The correct answer is: the distance between the objects and the amount of charge on the objects.
Alfredo makes a diagram to organize his notes about charging objects.

Which statement should he place in the region marked X?

It does not involve touching the objects together.
The objects develop opposite charges.
Electrons do not move between objects.
The objects have the same charge.
The statement that should be placed in the region marked X is: The objects develop opposite charges.
What is the name of the area around a charged object where the object can exert a force on other charged objects?

electric field
electric charge
electric induction
electric force
The correct answer is: electric field.
Why does Chelsea see sparks as she removes her clothes from the clothes dryer?

conduction
induction
static discharge
loss of protons
The correct answer is: static discharge.
Shareen performs a skit to model a method of charging. In the skit, a painter shakes her hand and gets paint on her.

How does the skit model a method of charging?

It models induction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.
It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
It models induction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
It models conduction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.
The skit models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?

The electric force increases because the amount of charge has an indirect relationship to the force.
The electric force increases because the amount of charge has a direct relationship to the force.
The electric force decreases because the amount of charge has an indirect relationship to the force.
The electric force decreases because the amount of charge has a direct relationship to the force.
The correct answer is: The electric force increases because the amount of charge has a direct relationship to the force.
The diagram shows two charged objects, X and Y.

2 balls marked X on left and Y on right. The left ball has arrows emerging in all directions but to the right and all arrows either point to the left or immediately bend toward the left after emerging. The right ball has arrows emanating in all directions but to the left and all arrows either point to the right or immediately bend toward the right.
Based on the field lines, what are the charges of the objects?

X: positive
Y: negative
X: negative
Y: neutral
X: negative
Y: neutral
X: positive
Y: positive
Based on the field lines described in the diagram, the charges of the objects are as follows:

X: negative
Y: positive
There is only X positive if Y is going to be positive.
Apologies for the mistake. You are correct. If the field lines for object Y point towards the right, it indicates that object Y is positively charged. Therefore, the correct answer is:

X: positive
Y: positive
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?

John charges the rod through induction, then charges the electroscope through friction.
John charges the rod through conduction, then charges the electroscope through induction.
John charges the rod through friction, then charges the electroscope through induction.
John charges the rod through friction, then charges the electroscope through conduction.
John charges the rod through friction, then charges the electroscope through conduction.
