Find the area of the triangle P Q R with Q(3,\ 2) and the mid-points of the sides through Q being (2,\ -1) and (1,\ 2) .

A charge Q located at a point vec r is in equilibrium under the combined field of three charges q_(1), q_(2) and q_(3) . If the charges q_(1) and q_(2) are located at point vec r_(1) and vec r_(2) respectively, find the direction of the force on Q due to q_(3) in terms of q_(1),(q_2), vec r_(1) vec r_(2) , and vec(r) .
