Student Exploration: Coulomb Force (Static)
Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes.
Vocabulary: Coulomb’s law, electrostatic force, vector
Activity A:
The effect of distanceGet the Gizmo ready :
●Turn on Show distance.
●Turn on show force vector for charge A
●Turn on Show vector notation
●Set qA to 10.0 × 10-4 C and qB to 1.0 × 10-4 C.
Question: How does distance affect the strength of the electrostatic force?
1.Observe : Move object A back and forth. How does the distance between the objects affect
the strength of the electrostatic force between them?
2.Gather data : Check that qA is 10.0 × 10-4 C and qB is 1.0 × 10-4 C. For each position of object A, record the distance between the objects and the force on object A.
Object AObject BDistance (m)|FA| (N)1
Distance2
(-2, 0)(1, 0)31001.00
(-5, 0)(1, 0)6250.25
(-11, 0)(1, 0)126.250.0625
(-14, 0)(1, 0)154C
3.As the distance increases, How does the force change?
4.Coulomb’s law is an equation that relates the electrostatic force between two objects to their distance and charge. The electrostatic force between two objects is proportional to the product of their charges. Combine that with what you have learned in this activity to complete Coulomb’s law below. Use the data you collected in the Gizmo to find the value
of the electrostatic constant, k. List the value and describe how you found it below. The units of k are newton · meter2 ÷ coulombs2, or N·m2/C2.Name: Period:
The closer they are, the stronger they repel from each other.
The force decreased when the distance increased.
