Question 1.
Consider a system with three-point charges arranged on the x-axis:
Q1 =−14μC at x1 =−6m
Q2 =−10μC at x2 =2m
Q3 = 20μC at x3 =8m
Coulomb's constant k=8.99×109 N m2 /C2
a. Draw clear free-body diagrams illustrating the electric force acting on each charge Q1
Q2 , and Q3 .
b. Calculate the magnitude and direction of the net electric force acting on the charge
Q1 due to the other two charges.
c. Determine the magnitude and direction of the net electric force acting on charge Q2
due to the other two charges.
