  3. Three tiny equal-mass magnets are placed on a horizontal frictionless surface at the corners of an equilateral triangle (all sides 2 m and all angles 600). When the magnets are released, they attract and quickly slide to a single point. What are the x and y coordinates of that point? (Before release, the y-axis passed through the top ball and the x-axis passed through the bottom balls.) 0 m 0 m 0 m 1 m 0 m .58 m 0 m .87 m .67 m .67 m 0 m .67 m y 2 m 2 m x 2 m x y
