The black rod is negatively charged because it has gained extra electrons, which are negatively charged particles, through a process called electron transfer. This excess of electrons makes the rod negatively charged relative to the surrounding environment.
Yes, the fur becomes negatively charged as it loses electrons to the glass rod. The glass rod becomes positively charged as it gains these electrons. The fur is negatively charged compared to the rod.
they repel remember, opposites attract and likes repel.
An electroscope can be charged negatively by using a negatively charged object, such as a rod rubbed with fur. When the negatively charged rod comes close to the electroscope, electrons from the rod are repelled and move into the electroscope, giving it a negative charge. This can be confirmed by observing the divergence of the leaves of the electroscope, which will spread apart due to the like charges.
A negatively charged rod can attract metal due to the phenomenon of electrostatic induction. When the rod approaches a neutral metal object, the negative charges in the metal repel, causing a redistribution of charges within the metal. This results in a positive charge accumulating on the side closest to the rod, creating an attractive force between the negatively charged rod and the positively charged side of the metal object. Thus, the rod appears to "attack" or attract the metal.
A carbon rod itself is not inherently negatively charged; it is electrically neutral under normal conditions. However, if it gains excess electrons, it can become negatively charged. In certain applications, such as in electrochemical cells or batteries, carbon rods can serve as electrodes where charge can accumulate, leading to a negative charge.
Yes, the fur becomes negatively charged as it loses electrons to the glass rod. The glass rod becomes positively charged as it gains these electrons. The fur is negatively charged compared to the rod.
The metal rod becomes negatively charged through a process called conduction. When a negatively charged object is brought near the metal rod, electrons on the surface of the rod are repelled, causing them to move to the end of the rod farthest from the negatively charged object. This redistribution of electrons creates a negative charge on the metal rod.
they repel remember, opposites attract and likes repel.
A black hole can be negatively charged, positively charged, or neutral depending on what has fallen into it.
If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.
When a negatively charged rod touches a neutral electroscope, electrons transfer from the rod to the electroscope, causing the electroscope to become negatively charged. This results in the leaves of the electroscope repelling each other and spreading apart, indicating the presence of an excess negative charge.
When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod, causing the rubber rod to become negatively charged. This transfer of electrons creates an imbalance of charge on the two materials, resulting in the rubber rod being negatively charged.
When polythene is rubbed with a duster, electrons from the duster are transferred to the polythene rod, giving the rod an excess of electrons and making it negatively charged. This transfer of electrons creates an imbalance of positive and negative charges on the surfaces, resulting in the rod becoming negatively charged.
Uncharged means that there are an equal number of protons and electrons. When the negative rod is held near the neutral metal ball, the electrons from the metal ball repel from the electrons on the rod bringing the protons closer to the rod causing the metal ball to be attracted to the negatively charged rod. It's called charging by induction.
If two negatively charged rods are brought close to each other, they will repel each other due to the like charges. The negative charges on the rods will create a force that pushes them away from each other.
When a glass rod is rubbed with wool, electrons are transferred from the wool to the glass rod, making the rod negatively charged. This transfer of electrons causes the glass rod to become statically charged, meaning it has an excess of negative charge.
A carbon rod itself is not inherently negatively charged; it is electrically neutral under normal conditions. However, if it gains excess electrons, it can become negatively charged. In certain applications, such as in electrochemical cells or batteries, carbon rods can serve as electrodes where charge can accumulate, leading to a negative charge.
