Which example provides a complete scientific description of an object in motion?

answer would be d.) i hope this

explanation:

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.)

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
