Question

Multiple choice, no details required or a graded. The figure shows four arrangements of three particles of equal mass. Two particle are shown as white spheres, one as a blue (dark) sphere. The distances between adjacent masses are cither d or 2d. In which arrangement is the gravitational force the blue particle the largest? in (1) in (2) in (3) in(4) small for all In which is it the smallest ? in(1) in(2) in(3) in(4) same for all In which direction does the gravitational force on the blue particle point ? 1up 2down 3more to the right than up 4 more up than to the right 5 none of these In which direction does the gravitational force on the blue particle point in arrangement ? Up down more to the right than up more up than to the right none of these
