Given are four arrangements of three fixed electric charges. In each arrangement, a point labeled P is also identified test charge, +q, is placed at point P. All of the charges are of the same magnitude, Q, but they can be either positive or negative as indicated . The charges and point P all lie on a straight line. The distance between adjacent items , either between two charges or between a charge and point P, are all the same. Correct order of choices in a decreasing order of magnitude of force on P is
