A mass is at the center of a square, with four masses at the corners as shown.

Rank the choices according to the magnitude of the gravitational force on the center mass.

Locate the center of mass.

Center Of Mass

The figure shows four arrangement of three particles of equal masses. Rank the arrangement according to the magnitude of the net gravitational force on the particle m, greatest first.

Center of mass may lie

Find the center of mass of the four point masses as shown in figure.

Three particles, two with mass m and one with mass M, might be arranged in any of Rank the configuration according of the gravitational force on M, least to greatest.

Three particles, two with mass m and one with mass M, might be arranged in any of Rank the configuration according of the gravitational force on M, least to greatest.
