An object on a tabletop moves in a straight line, in a direction that forms a \(60^{\circ}\) angle with a ruler. The position of the object read from the ruler was \(10\text{ cm}\) when it started moving. The object then stops when its position read from the ruler is \(32\text{ cm}.\) What is the displacement of the object?
