B. DATA ANALYSIS AND COMPUTATION

1. Attach your graphs at the end of the activity sheet. Write in Table 3 the value of the Coulomb constant you found from your graphs.

2. Solve for the percentage error and percentage accuracy of the Coulomb constant you obtained for each part. Show complete solution.
