Two charges are placed a certain distance apart such that the force that each charge experiences is 20 N. If the distance between the charges is doubled, what is the new force that each charge experiences?
Possible Answers:
There is no way to determine the new force
Correct answer:
Explanation:
To solve this problem, we'll need to utilize the equation for the electric force:
We're told that the force each charge experiences is 20 N at a certain distance, but then that distance is doubled. Thus, the new electric force will be:
What is the force experienced by a
Possible Answers:
The point charge experiences no force
Correct answer:
Explanation:
The equation to find the force from two point charges is called Coulomb's Law.
In this equation,
Now, we just plug in the numbers. Note: the charge values are in microcoulombs (the Greek letter
Therefore, the force experienced on either charge is 0.216N of force.
You have two point charges,
Possible Answers:
Correct answer:
Explanation:
The equation for the force between two point charges is as follows:
We have the values for
Therefore, the value for the second charge is
Two objects in space are placed
Possible Answers:
Correct answer:
towards each other
Explanation:
Use Coloumb's law:
First, convert the charges into coulombs.
Plug in values into Coulomb's law.
Negative electric forces indicate attractive forces. Alternatively, we can reason that since one charge is positive, and the other is negative, the charges will attract.
