A lightweight plastic rod has a mass of 2.0 kg attached to one end and a mass of 2.5 kg attached to the other end. The rod has a length of 1.20 m. How far from the 2.0-kg mass should a string be attached to balance the rod

The distance from the 2.0 kg mass at which a string should be attached to balance the rod is 0.67 m.

To calculate the distance at which the string must be attached to balance the rod, we use the formula below.
