Question

Two point charges are located on the x-axis of a coordinate system: 1 q nC =1.0 is at x cm = +2.0 , and 2 q nC = −2.0 is at x cm = +4.0 . What is the total electric force exerted by 1 q and 2 q on a charge 3 q nC = 5.0 at x = 0?​

Answer 1

Answer:

Please refer to the above attachment

Answer 2

Answer:

“9. =1.- nC”

but You can calculate Yourself in easy steps:

Calculate force F31 which Q1 acts to Q3

Calculate force F32 which Q2 acts to Q3

Then force F3=F31+F32 is the force wanted.
