Math Problem Statement
-
Set q1 to 5C and fix the distance between the two objects at 6 cm, record them in table 2.
-
Change the charge of object 2 as shown in table 2 and for each q2 record the electric force between the two objects.
-
Plot a graph in Excel relating FE (y-axis) and q2 (x-axis). Sketch the graph or insert a screenshot. Comment on the graph’s appearance.
-
Find the slope of the graph and use it along with Coulomb’s Law to find the electric constant k.
-
Calculate the percentage error for your measured value of k (known=8.99 × 109 Nm2/C2) slope 12.483
