Typically, a pith ball electroscope is charged if the pith balls are either attracted or repelled from each other. This indicates an excess of positive or negative charge. Without observing the behavior of the pith balls, it may not be possible to determine the charge of the electroscope just by looking at it.
What else can I help you with?
Is it necessary for a charged body to touch the ball of the electroscope for the leaves to diverge?
No, charged body doesn't need to touch the ball. The presence of a charged body near the electroscope is enough to cause the leaves to diverge due to the transfer of charge.
What kind of charge the electroscope can detect?
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
What are the kind of electroscope?
There are two main types of electroscopes: gold-leaf electroscope and pith-ball electroscope. Gold-leaf electroscope uses thin gold leaves to detect electric charges, while pith-ball electroscope uses lightweight balls made of pith or other materials that can be attracted or repelled by electric charges.
Why ball in the pith ball electroscope has to have a small mass?
The ball in a pith ball elecroscope is small because the ball must be able to move with little forces. If the ball had a large mass it would be difficult for a small force of attraction to occur.
Principle of electroscope and types of electroscope?
An electroscope is a device used to detect the presence of electric charges. It works on the principle of charge induction, where like charges repel each other causing a leaf or needle to diverge. The two main types of electroscopes are the gold-leaf electroscope, which uses thin gold leaves, and the pith-ball electroscope, which uses lightweight balls of plant material.

What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
How could you use a pith ball electroscope to learn which material holds onto its electrons more strongly?
You could use the pith ball electroscope to test different materials by charging it with the materials and observing the behavior of the pith ball. If the pith ball is deflected more when charged with a particular material, it indicates that the material holds onto its electrons more strongly.

How can you test for the presence of a charge?
One way to test for the presence of a charge is by using an electroscope. When a charged object is brought near the electroscope, it causes the leaves to diverge due to the interaction of the charges present. Another method is by using a charge sensor, such as a metal ball attached to a string, which will be attracted or repelled depending on the presence of charge.
Why do the leaves of an electroscope always diverge to the same extent when a charged body is brought in contact with its disc?
The electroscope has the little ball on top of the "input" rod. Dump some electrons on the ball and the charge will be distributed down inside to the little leaves. Electrons don't like each other. Law of electrostatics, ya know: opposites attract and likes repel. The electrons collect on the leaves and electrostatically push against each other. The electrostatic force is sufficient to move the light foil.
Predict what would happen if you touched the knob of a positively charged electroscope with another positively charged object?
In order to test the presence of a charge on an object, the object is brought near to an uncharged pith ball. If the object is charged, the ball will be attracted to it and move toward it. The attraction occurs because of induced polarisation of the atoms inside the pith ball. The pith is a nonconductor, so the electrons in the ball are bound to atoms of the pith and are not free to leave the atoms and move about in the ball, but they can move a little within the atoms. If, for example, a positively charged object is brought near the pith ball, the negative electrons in each atom will be attracted and move slightly toward the side of the atom nearer the object. The positively charged nuclei will be repelled and will move slightly away. Since the negative charges in the pith ball are now nearer the object than the positive charges, their attraction is greater than the repulsion of the positive charges, resulting in a net attractive force. This separation of charge is microscopic, but since there are so many atoms, the tiny forces add up to a large enough force to move a light pith ball. source: http://en.wikipedia.org/wiki/Electroscope
In experiments involving a pinball electroscope what causes the pithball to move?
The movement of the pithball in a pinball electroscope is caused by the buildup of static charge on the object being tested. When an object with a charge is brought near the electroscope, it induces a charge on the pithball causing it to move due to electrostatic forces.
What causes a pithball to move in an experiment involving a pithball electroscope?
A pithball moves in response to the electrostatic force between the charged object and the pithball. When a charged object is brought close to the pithball, the charges on the object induce a separation of charges in the pithball causing it to become attracted or repelled, leading to its movement.
