Quick hack to verify this rage comic http://wheresmysammich.com/images/34082.jpg for numbers 0-100000. Counter intuitive at first glance but makes sense on closer look

The masses and coordinates of three spheres are as follows: 28 kg, x = 1.00 m, y = 2.50 m; 44 kg, x = -2.00 m, y = -1.75 m; 54 kg, x = 0.00 m, y= -0.50 m. What is the magnitude of the gravitational force on a 18 kg sphere located at the origin due to the other spheres?

self.m = m
self.x = x
