How is the electroscope used for testing the types of charge?
The electroscope consists of a metal rod with thin gold or aluminum foil leaves attached at the end. To test the type of charge, you can bring a charged object close to the knob of the electroscope. If the leaves of the electroscope diverge, it indicates that it has acquired a charge of the same type as the object being tested. If the leaves collapse or move towards each other, it indicates an opposite charge.
What force causes the leaves in an electroscope to repel each other?
The leaves in an electroscope repel each other due to the buildup of like electric charges on them. This is the result of contact with a charged object or being placed in an electric field, causing the leaves to acquire the same charge and thus repel each other.
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
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 gas is produced when a battery is being charged?
When a battery is being charged, hydrogen gas is produced.
Who see the electron with electroscope?
An electroscope is a device that can detect the presence of electric charge, including electrons. When a charged object is brought close to the electroscope, the electrons on the device are repelled or attracted, causing the leaves to diverge. This divergence indicates the presence of electrons on the object being tested.

What does direct observation do?
Observation changes the force being observed.
What are the types of observation in socialwork research?
The types of observation in social work research include direct observation, participant observation, structured observation, and naturalistic observation. Direct observation involves watching behavior without interaction, while participant observation involves the researcher being part of the setting being observed. Structured observation uses a predetermined set of behaviors to observe, and naturalistic observation involves observing behavior in its natural setting.
What is the word for to insist of being recognized?
The word for insisting on being recognized is "assert."
What is covert observation?
covert observation Participant observation carried out without the explicit awareness and agreement of the social unit being studied.
