What would happen if you tried to put two balloons with the same charge together?
When rubbing a balloon with a wool cloth, it puts negative charges on the balloon. Negative charges attract to positive charges. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
Why do opposite charges attract each other?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.
Can two like charges attract each other if yes why?
yes they can attract each other when one of them is very very large than the other then the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction. and hence attraction takes place.
Which of the following Cannot be charged easily?
Copper is a highly conducting materials. Therefore, a copper rod cannot be charged easily by friction.
When can you say that a body is charged?
Answer. when a body connect with electricity then we say that the body is charged.
How does a body get charged?
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
How will you test the nature of charge present on a body?
Detect charge: Body under test is touched with the metal cap. If the leaves diverge, the body is charged and if there is no effect on leaves, then the body is uncharged. If the leaves diverge further, the body has same charge(positive) and if the leaves come closer to each other, the body has opposite charge(negative).
How does Electroscope detect the charge?
The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage.
How can you use an Electroscope to detect the charge on a body?
Complete answer: To detect the presence or absence of charge on a body, we bring the body close to the gold leaf electroscope and touch it with the cap of the device. If the body has charge, then the two leaves of the electroscope also get similarly charged.
What happens when a positively charged rod is brought near a neutral plastic ball?
Protons are never transferred in electrostatic activities. In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively. It is touched by a positively charged metal rod. As a result, the metal sphere becomes charged positively.
What causes the foil leaves to move apart when the charged rod touches the metal ball?
The metal will push the foil leaves apart because the leaves have the same charge. Since the electroscope is a conductor, electrons move down to the leaves, being repelled byt he negative charge of the insulator. The sphere is thus temporarily positively charged.
