Given are four arrangements of three fixed electric charges. In each arrangement, a point labelled 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 distances 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
