How charging by induction can make two metallic spheres oppositely charged?
sphere
Which part of an atom is involved in charging objects?
The parts of an atom that are involved in charging objects are the protons and the electrons. Protons are positively charged, while electrons are negatively charged.
How is charge by induction similar from charge by conduction?
Both conduction and induction involve a movement of electrons. Conduction is the transfer of electrons from a charged object to another object by direct contact. Induction does not involve direct contact. Instead, induction is the movement of electrons from one part of an object to another as a result of the electric field of the second object.
Why do objects become positively or negatively charged?
An item becomes positively or negatively charged through losing/gaining electrons. As electrons are lost the item becomes positive, and as electrons are gained the item becomes negative. (Electrons are negative charges and protons are positive charges.) An item cannot lose protons, as protons are fixed. Gaining/losing electrons can be gained by charging by friction, contact, or induction (through the air).
Which of the following particles is negatively charged?
An electron is negatively charged.
What are the two ways to transfer electrical charges?
Friction - charging something by rubbing it against another object Induction - charging something by coming close to charged object, but not touching Conduction - charging something by touching a charged object
When can charging by contact be dangerous?
Charging by conduction involves touching a negatively charged object to a neutral object. It can be dangerous when using a part of the human body as the circuit .
Describe whether the comb is charged by conduction or induction?
induction
What is the difference between charging by conduction and induction?
Charging by Induction:- 1. No physical contact. 2. No exchange of charge. Charging by conduction:- 1. Two objects must be in physical contact. 2.Transfer of charge takes place. Difference between charging by induction and charging by conduction: Induction Conduction 1. In this process there is no physical contact between the objects. 1. The conducting surface is connected to a charged object to transfer the charge. 2. The net charge on the object is zero since equal amount of opposite charge is accumulated on the side away from the side where a charge is induced. 2. The net charge on the object changes after the charging process since there is a transfer of charge.
When a metal ball is charged by induction using a negatively charged plastic rod what is the sign on the charge acquired by the ball?
There exists and answer to this problem if you state the following: After the ball has been in presence of the negatively charged rod, the metal ball is either grounded or discharged by another conductor leaving the original metal ball with a positive charge, hence the name charging by induction.
If you were given a positively-charged rod to charge an object by induction what charge will the object get?
When an object is rubbed with a charged rod, the object shares the charge so that both have a charge of the same sign. In contrast, charging by induction gives an object the charge opposite that of the charged rod. so your object would be negatively charged.
When Charging a neutral object by touching it with a charged rod is called?
It's called charging by conduction.
What is a charging a neutral object by bringing it close to a charged object?
induction
How charging by induction can make two metallic spheres oppositely charged?
sphere
The metal rod becomes negatively charged as well through which process?
conduction
Can you say that a charged object attracts an uncharged object by first charging it by induction why or why not?
Cönsider a negatively charged object be placed at a fixed position ,now a neutral or uncharged object is slowly introducing into the field which is produced by the electrons in negatively charged object.... And now according to the law of charges opposite charges attract each other similar thing taking place here the electrons present on the negatively charged object attracts the positive charge in neutral object by separting the charges inside the object wich is called induction as soon as the neutral object enters into the field produce by negatively charged object ...,and then it attracts...
Three methods to charge an object?
Charging by friction - this is useful for charging insulators. If you rub one material with another (say, a plastic ruler with a piece of paper towel), electrons have a tendency to be transferred from one material to the other. For example, rubbing glass with silk or saran wrap generally leaves the glass with a positive charge; rubbing PVC rod with fur generally gives the rod a negative charge. Charging by conduction - useful for charging metals and other conductors. If a charged object touches a conductor, some charge will be transferred between the object and the conductor, charging the conductor with the same sign as the charge on the object. Charging by induction - also useful for charging metals and other conductors. Again, a charged object is used, but this time it is only brought close to the conductor, and does not touch it. If the conductor is connected to ground (ground is basically anything neutral that can give up electrons to, or take electrons from, an object), electrons will either flow on to it or away from it. When the ground connection is removed , the conductor will have a charge opposite in sign to that of the charged object.
