An electroscope can be used to determine the charge of an object.
An electroscope would detect an electrical charge.
In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge. In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope. If the leaves diverge more, then 'X' has positive charge.
by induction
Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines.
it may be positive or negative hope this helped :)
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.

Alll an electroscope does is tell you if there is charge

Neutral charge describes the charge of an atom before any electrons are transferred.

...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
your body is conducting the charge away from the electroscope, neutralizing the charge
when a substance is electrically charged it has either too few or too many electrons. when the electroscope is brought near a charged object the electrons 'jump' if the substance had too many electrons then the extras would 'jump' to the electroscope giving it a negative charge if the substance had too few electrons then the electrons from the electroscpe would 'jump' to the substance, giving the electroscope a positive charge
