An electroscope detects the static electrical charge on an object. If an object with a electrical charge is touched to the knob on top this charge is transferred to the rod and in turn to the metal leaves in the jar. Opposite charged objects attract and same charged objects repel. The charge on both leaves is the same polarity so they repel each other.
The metal rod is a good conductor. Hence when we touch it will a charged electroscope,the repeling charges will flo through it and our body and reach th ground.so the charge disappears and the leaves collapse
When we touch a charged electroscope with our fingers, the excess charge on the electroscope is neutralized by our body, causing the electroscope to discharge and lose its charge. As a result, the leaves of the electroscope will collapse back together.
When a charged rod is brought near an electroscope with the opposite charge, the positive and negative charges in the electroscope are attracted to the rod. This causes the leaves to come closer together as the negative charges in the leaves are attracted to the positively charged rod. This movement indicates that the electroscope has detected a charge.
The sphere, rod, and leaves of an electroscope need to be conductors to allow the flow of electric charge. When they come into contact with a charged object, electrons can move freely within the conductors, causing the leaves to diverge due to electrostatic repulsion. If they were insulators, the charge would not be able to distribute and the electroscope would not function.
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.

All of the metals attract and repel, but if a: negative and positive come together= attract positve and a negative come together= attract negative and negative come together= repel positive and positive come together= repel
Certain materials like rubber, plastic, and wood are known to repel against metal due to their non-conductive properties. Additionally, some metals are naturally resistant to corrosion and may repel other metals when they come in contact. It's important to take into consideration the specific properties and interactions between the materials involved.
they repel
Oil won't allow oxygen or water to come in contact with the metal surface. Oil forms a barrier due to it's hydrophobic nature, which allows it to repel the oxygenated water. You must have oxygen and H20 in order to corrode or rust most metal surfaces.
They repel
The oil leaves a thin film on a metal surface. This allows the moving parts to come in contact without producing friction which produces heat. It also reduces the amount of metal that is worn away between contact with two metal surfaces.
