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