A charge Q located at a point `rarrr` is in equilibrium under the combined electric field of three charges `q_1, q_2 and q_3` if the charges `q_1, q_2` are located at the points `rarrr_1` and `rarrr_2` respectively, find the direction of the force on Q, due to `q_3`, in term of`q_1,q_2,q_3 rarrr, rarrr_1, and rarrr_2`
