A force of 200 N at 55 degrees is acting on an object. What is the magnitude and direction of the horizontal component of this force?

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.)

connect the batteries in series and hope
