Solution
A charged object can be detected with an electroscope.
Explanation:
This instrument is used to detect electrical charge (positive or negative). When an object is electrically charged, its reaction in the electroscope indicates whether the object is charged or not. The electroscope has a filament or blades, which can move closer or farther from each other when charged, thus indicating the charge.
