What happens when the two cans are moved closer together what happens when they are separated?
When the cans are separated, they each have an excess of opposite charge. But when they are brought back together again with the balloon no longer nearby, there is an attraction between this excess of charge. This causes another movement of electrons back to the original neutral state.
What cause the cans to move?
Science Principle Moving air has a lower pressure than stationary pressure. This difference creates an imbalance of pressure on the cans; the pressure on the outside is higher than in between. This difference causes the cans to move toward the area of lower pressure.
Why did the two rubbed balloons repel each other?
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.
What happens when a charged object is brought close to a neutral object?
In the induction process, a charged object is brought near but not touched to a neutral conducting object. The presence of a charged object near a neutral conductor will force (or induce) electrons within the conductor to move. The flow of electrons results in a permanent charge being left upon the object.
How is the pith ball charged when it is repelled by the glass rod?
– Use glass rods rubbed down with a piece of silk. (Glass rods will lose electrons in the process.) When gently sliding glass rod over the pith ball, electrons from the pith ball will transferred to the positively charged glass rod and pith ball will gain a net positive charge.
What would you see if the pith ball touches the positively charged rod?
When a charged rod is brought close to the pith balls, their charges polarize. If they come in contact with the charged rod, they can inherit the same sign charge. Since like charges repel. when similarly charged, the pith balls behave like siblings and refuse to touch each other.
What will happen if you touch the ball of a charged Electroscope with your finger?
When we touch the metal top of a charged electroscope with our finger because metal top and our body are conductors will try to come to a common potential. This phenomena is called sharing of charges or charging by touching.
