here is your answer
THE MAGNITUDE OF ELECTROSTATIC FORCE OF ATTRACTION BETWEEN TWO POINT CHARGES IS DIRECTLY PROPORTIONAL TO THE PRODUCT OF MAGNITUDE OF CHARGES AND INVERSELY PROPORTIONAL TO THE SQUARE OF DISTANCE BETWEEN THEM.
THE FORCE IS ALONG THE STRAIGHT LINE JOINING THEM.
WHILE DEALING WITH COLOUMB'S LAW IN VECTOR FORM, SIMPLY CALCULATE THE STRENGTH OF ELECTRIC FORCE AS YOU WOULD WHEN YOU DEAL WITH IT IN ITS NON VECTOR FORM AND THEN ATTACH A DIRECTION TO THE FORCE BASED ON THE POSITION AND TYPES OF CHARGES INVOLVED.

Coulomb’s law: The electrostatic force between two stationary point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Vector form of Coulomb’s law: if ri and rj are position vectors of two point charges Qi and Qj and Fij is the force exerted by Qj on Qi, then
Fij=kQiQj(ri-rj)/[|ri-rj|]^3.
