Two positive point charges, each of which has a charge of 4.3E-9 are located at y=+.10m and y+-.10m.
A) Find the magnitude of the resultant electrical force on a charge of 9E-9 located at x= .65m (Coulomb is 8.98755E9)
B) What is the direction of this force (measured from the positive x-axis as an angle between -180 degrees and 180 degrees, with counterclockwise positive)?
