Mell What kind of charging does an electroscope use?
neutral charge
The electroscope has a net neutral charge and the rubber rod has a net negative charge. If they are brought into contact, they will both take a net negative charge.
Can electroscope be charged by induction?
Charging an Electroscope by Induction Using a Negatively Charged Balloon. In the induction process of charging, a charged object is brought near to but not touching the electroscope. The presence of the charged object above the plate of the electroscope, induces electrons within the electroscope to move accordingly.
What happens when a positive rod touches an electroscope?
Similar to the results of a negatively charged rod, if a positively charged rod is brought near the knob of a neutral electroscope, it will attract some electrons up from the leaves onto the knob. That process causes both of the leaves to be positively charged (excess protons), and the leaves will diverge.
What are some examples of charging by induction?
If a rubber balloon is charged negatively (perhaps by rubbing it with animal fur) and brought near the spheres, electrons within the two-sphere system will be induced to move away from the balloon. This is simply the principle that like charges repel.
What is the working of an electroscope?
WORKING OF AN ELECTROSCOPE : When a charged object touches the metal knob, electric charges travel down the rod and into the leaves. The leaves spread apart, indicating the presence of an electric charge. Since the charge on both leaves is the same the leaves repel each other and spread out.
What is the applications of electroscope?
Following are the uses of electroscope: It is used to detect the static charges. The nature of electric charges can be determined using an electroscope. The magnitudes of two different charges can be compared using an electroscope.
How to determine the sign of a charged object using the electroscope?
Move the charged object near the top terminal of the electroscope. Do NOT move it so close that it transfers charge. If the object has a positive charge, it will pull electrons up to the top terminal. This will cause the leaves of the electroscope to be more positively charged, causing them to move further apart.
What is the function of an electroscope?
The electroscope is an instrument for detecting an electric charge by measuring mechanical forces between two charged bodies. Does an electroscope identify if an object has a positive or negative charge or does it just indicate that an object has a charge?
Can a positive object be on an electroscope?
The electroscope was formerly neutral but a positive object has touched it and the leaves separated, so I considered the electroscope are positively charged.
How does a negative charge affect an electroscope?
This will cause the leaves of the electroscope to be more positively charged, causing them to move further apart. If the object has a negative charge, it will repel electrons from the top terminal. This pushes electrons down to the leaves, causing them to be less positively charged, causing them to drop towards each other.
