What does this picture illustrate?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

like poles repel so keep pushing north to north and repels funny to see this

what is the actual question though?

technology is the application of the knowledge gained by science.
