1Three masses are arranged in the (x, y) plane as shown. 7kg at (-3,1) 8kg at (0,0) 9kg at (1,2) What is the magnitude of the result- ing force on the 8 kg mass at the ori- gin? The universal gravitational constant is 6.6726 × 10^−11 N · m^2/kg^2 . Answer in units of N. part 2; Select the figure showing the direction of the resultant force on the 8 kg mass at the origin. all the mutliple choice aswers show a ray rotating a different amount around the origin please help, i was sick and missed 2 days of physics and dont understand even wath the question is askeing if you could even expain it to me it would be wonderful thanks!
