Hi guys, Need some help.. The case is, there are 2 circles, 1 circle is bigger than another one. Let's say the bigger one is circle Q with R1 diameter the smaller one is circle P There is black circle Z which position is constant. In the first position (the left side), the centerpoint of both circles are same and the ball and yaxis form 45 degree angle. B is the shortest distance between black dot Z and smaller circle. In the second position, the black circle stays still on the former position, same with the circle Q. The question is, can we know the "C" value if we know the value of A, B, R1, and R2 B or C = the closest distance from black circle Z to small circle. thanks (lol, i'm sorry for what i've posted earlier, i was super sleepy)
