An electroscope can be used to determine the charge of an object.
An electroscope would detect an electrical charge.
Like charges repel and unlike charges attract each other this is the fundamental principle used in an electroscope to detect presence and amount of charge. There are mainly 2 tpes of electroscopes pith ball electroscope and gold leaf electroscope
...Guys...This is the answer of question...it simple! If we grounded the electroscope..whatever the charge on leaves are, positive or negative (as it depends with which charge you electrolyse the electroscope), if its positive and ground is negative (attraction) or if same + + so repultion

An electroscope can be used to determine the charge of an object.
An electroscope would detect an electrical charge.
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
When the probe of the electroscope is brought near a charge, free charges in the electroscope rod are either attracted to or repelled from the probe. This leaves a net charge at the other end of the rod (since the electroscope as a whole is electrically neutral). Since the other end of the rod is charged, its parts repel each other (since like charges repel). Thus, the gold-leaf indicators spread apart.

It indicates that the leaves of the electroscope have received a charge.
An electroscope is an instrument for detecting the presence of static electricity.
