A charged electroscope is used to find the nature of a charge of an object.
The electroscope is charged with a known charge. Then the object is brought near it. The nature of the charge can be determined on the basis of the response of the object. It may either be attracted or repelled. Depending on this the nature of the charge of an object can be known.

The answer to your question is "charged electroscope". It is used to detect the nature of charge on an object. It has a brass rod which has two thin gold leaves attached to its lower end. The movement of the leaves detect the nature of the charge present on the body. When any charge is transferred to an electroscope, It spreads in the leaves and they diverge.
In order to detect the kind of charge on a charged body, the electroscope will have to be first charged either with a positive charge or with a negative charge. After charging the electroscope, Bring the body under test near the charged electroscope. If the divergence of the leaves increases then the body will have the same charge as that on the electroscope. On the other hand, if the divergence of the leaves decreases, then the charge on the body is opposite to that present on the electroscope.
Hope it will help you.
