The electroscope can't distinguish the two cases.

How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
What makes an object positively or negatively charged?
Step one. Charge the electroscope by the induction method. A rod is used of opposite sign to that required on the electroscope . The rod is brought near to the cap so that the leaf diverges by the amount desired, and the electroscope is momentarily earthed by touching it with a finger. The rod is then removed, leaving the electroscope charged. (If the charged rod used is Benoite this leaves a positively charged electroscope, if a glass rod is used then the result is negatively charged electroscope) Step two Now use the object of unknown charge, A charge of the same kind as that on the electroscope will cause an increase while a charge of the opposite kind will cause a decrease in leaf divergence when the object is brought near to the electroscope. You must bring the object down from a good height, and move it slowly down towards the cap so any change in divergence will not be overlooked before the object becomes to close to the cap. Bringing the object down too quickly and too close to the cap could lead to a false reading. Source(s): A. F. Abott Ordinary Level Physics
Uses of an electroscope?
An electroscope can be used to determine the charge of an object.
Is there any negative charge on a positive charged object?
Any "object" larger than elementary particles consists of positive and negative charges. If your object has a negative charge, it simply has more particles with a negative charge than particles with a positive charge.
How the charges on the body may be determined by using an electroscope?
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
Does an electroscope identify if an object has a positive or negative charge or does it just indicate that an object has a charge?
Alll an electroscope does is tell you if there is charge

Is an object without a charge repelled by both positive and negative charges?
Positive and negative charges would have not effect on an object without charge.
Is it true that an object with a positive charge will attract another object with a negative charge?
yes

Is an object's net charge positive or negative if it loses electrons?
positive
How does an object get a positive charge or negative charge?
By loosing or gaining and electron.
Is charge the measure of extra positive or negative particles in an object?
positive
