point charge 1=5.00microcoulombs is located at x=0.22 m, and point charge 2=-3 microCoulombs is at x=-1.200 m. a positive charge 3 is located at the origin.
a. what must be the magnitude of charge 3 for the resultant force on it to have magnitude 5.00microCoulombs?
b. what is the direction of the resultant force on charge 3?

i need the solution for dis...
thankz...
