How can gold leaf electroscope be used to detect an electric charge?
When a charged object is brought close to the metal disc of a gold leaf electroscope, the like charges are repelled to the gold leaves, causing them to diverge due to the electrostatic force. This divergence can indicate the presence of an electric charge.
If a postivively charged rod is brought near the knob of a positively charged electroscope the leaves of the electroscope will?
The leaves of the electroscope will repel each other and diverge further apart. This is because like charges (positive) repel each other, causing the leaves to move away from each other due to the force exerted by the positively charged rod.
What is an electroscope and how does it detect charge?
An electroscope is a device used to detect the presence and magnitude of electric charge. It typically consists of a metal rod with thin metal leaves attached to the bottom. When a charged object is brought close to the electroscope, the like charges in the electroscope are repelled to the leaves, causing them to diverge, indicating the presence of charge.
When a rod is brought near a neutral electroscope the leaves diverge what best describes the charge on the rod?
it may be positive or negative hope this helped :)
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.
What would happen if you touched a positive electroscope with a positive rod?
The leaves of electroscope will diverge a little more because more positive charges will flow from a positive rod
Why is it important to touch a charged object to the metal rod of an electroscope and not to the rubber stopper?
Touching the charged object to the metal rod allows the electrons to transfer easily to the electroscope, causing the leaves to diverge due to like charges repelling. The rubber stopper acts as an insulator, preventing the transfer of charge effectively and resulting in no movement of the leaves.
How does an electroscope work to detect static electricity?
An electroscope operates by using a delicate metal leaf that is repelled by like charges. When the electroscope is charged with static electricity, the metal leaf will diverge due to the force of the similar charges. This physical movement is an indication of the presence of static electricity.
Does a radioactive particle moving through the air near an electroscope cause the leaves of the electroscope to move together?
when the radio active particle moves through the air, it gets charged. As a radio active particle gets negative charge, and the air around it gets positive charge, then the few electrons from the negatively charged particle goes to positively charged one to make the charges equal. (the more friction you apply, the more charge it gains) now the radio active particle gained positive charge compared with other particles. If the radio active particle flows over the electroscope and is near it within a limit, then the leaves may move together if the electroscope had been charged negative, else the leaves are charged positive then the leaves would diverge further . as the radio active particle is not actually touching the electroscope, the radiated energy from the radio active particle reaches the electroscope, and hence the charges would not transfer but the effect would be there until you take the radio active particle away. answered by K.Sreram from India
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 is gold leaf electroscope?
INVENTOR OF THE GOLD-LEAF ELECTROSCOPE:-Englishmen Sir Abraham Bennet (1786 Anno Domini)PRINCIPLE OF A GOLD-LEAF ELECTROSCOPE:-A gold-leaf electroscope is a simple device which is used to identify the electric charge present in a body.CONSTRUCTION OF A GOLD-LEAF ELECTROSCOPE:-1) A gold-leaf electroscope is a metallic disk attached to one end of a copper rod.2) To the other end of the copper rod, two thin gold metal leaves are attached. (Usually of gold. Can also be of another metal.)3) The side of the copper rod with the thin gold leaves is fitted inside a conical flask, through a non-conducting rubber-cork.4) The thin gold leaves are used in a electroscope to make it more sensitive.WORKING OF A GOLD-LEAF ELECTROSCOPE:-1) If an uncharged body is brought and touched on the metallic disk, we notice no change in the golden leaves.2) If a charged body (positively or negatively charged) is brought and touched to the metallic disk of the gold-leaf electroscope, it attains the same charge as that of the charged body touched to the metallic disk by the property of transmission of charges from one charged substance to another substance.3) Therefore, the golden leaves in the electroscope also attain like charges and diverge from each other due to the repulsion.4) The repulsion of the golden leaves in the electroscope is the test for finding out that whether a body is charged or not.5) If we touch any of the charged bodies, the charge escapes from our body directly to the earth through our legs.6) The charged body thus loses it's charge and becomes neutral.
What is to diverge?
to be un-normal. Example: she is diverge from everyone else
