The graph that represents the relationship between the magnitude of the electrostatic force and the magnitude of the electric field strength.
What is a direct positive relationship?
100
Opposites do this.
What is attract?
100
What does the Conservation of charges state?
What is charges are neither created or destroyed, the overall charge must be conserved? Example...
100
When can we use Coulombs law (both criteria needed)
What is spherically symmetrical charges?
200
The electric field intensity at a point where a proton experiences an electrostatic force of magnitude 2.3 x 10^-25 N
What is 1.44 X 10^-6?
200
If you have two point charges of magnitude q1 and q2 separated by a distance r, the magnitude of the Force between them is F, if you double q1, quadruple q2 and double the distance what is the new force in terms of F
What is 2F?
200
Like charges do this
What is repel?
200
If sphere A has a charge of +8C and sphere B has a charge of -2C what charge will sphere A have after contact with sphere B?
What is +3C?
200
If a negatively charged rod is brought in contact with an electroscope. As the rod gives up electrons the number of protons does this.
What is remains the same? Why...
300
The potential difference between points A and B of a proton in the electric field that gains 8.35 x 10^-14 J?
What 5.22 x 10^5?
300
Draw an electroscope after it has made contact with a negative rod.
What is sphere and leaves are all negatively charged?
300
What is a greater force, gravitational attraction or electrostatic?
What is electrostatic? Explain why...
300
Explain charge by conduction using a positively charged rod.
If you have a positively charged rod and you touch the rod to a neutral object the object will also become positively charged as electrons more from the neutral object to neutralize the positive charge.
300
Sketch field lines between two oppositely charged points (at least three with arrows)
What is arrows going from positive to negative in straight lines?
400
The total amount of work required to move a proton through a potential difference of 100 V.
What 1.6 x 10^17 J?
400
if you have a charge of -5C how many excess electrons do you have?
What is - 3.125 x 10^19?
400
The electrostatic force between a charge of 3 x 10^-5 and 6 x 10^-6
What is 18 N?
400
Explain charging by induction with a negatively charged rod.
As you more a negatively charged rod closer to an object the object becomes polarized and the positive charges are attracted to the negative rod. (can draw a picture too)
400
Is it possible to have a charge of 2.0 x 10^-19 C? Explain fully
What is no because the charges have to be in multiples of one elementary charge, we cannot have a fraction of an elementary charge?
500
The work done when 5.0 C is raised in potential by 1.5 V
What is 7.5 J?
500
Draw an electroscope that has a positive rod brought close to it but not touching
What is a negative sphere and positive leaves?
500
The force on a proton in a uniform electric field whose strength is 2 x 10^5
What is 3.2 x 10^-14N?
500
Explain what happens when a negatively charged rod gets close to a neutral object.
It is attracted to it. Bonus What happens once it touches the neutral object?..
500
Sketch the electric field lines on a single negative point charge
what is a circle with a minus sign and straight lines radiating from it?
