2.1 A 50 kg mass at position i, =(7 m, 0m) is attracted to a 100 kg mass at position i0=(4m, 0m) and a 100 kg mass at position i,00=(10m, 0m) . Determine the gravitational force the 100 kg masses exert on GmM. the 50 kg mass. Reminder F= 2.2 A uniform plate has its boundary consisting of two concentric circles of inner and outer radii p and q, respectively, as shown in the sketch below. Determine the gravitational force which the plate exerts on a particle of mass M at its centre as shown in the sketch below.
