Two small balls are fixed at both ends of a rod with length L, and make a circular motion around a point o on the rod. The speed of small ball 1 is V1, and the speed of small ball 2 is v2. Calculate the distance from O to 2

Let the distance between O and 2 be x, then the radii of motion of the two balls are l-x and X respectively. If the angular velocity of the two balls is equal and V1 / (l-x) = V2 / x, then x = v2l / (V1 + V2)
