Rubbing the balloon onto your hair or onto the wool fabric
adds electrons to the balloon
and causes the balloon to become negatively charged. Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)
Why does a balloon becomes negatively charged when rubbed?
When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge.
The rubber gained electrons
giving it a negative charge. Since electrons have a negative charge, the balloon now has a negative charge.
When a balloon is rubbed with wool the balloon becomes negative and the wool positive what happened?
When you rub a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge. If both balloons are rubbed with wool, they will both have same charge (negative) and therefore
will repel each other
.
What happens to the balloon when you rub it with wool?
Rubbing the balloon against hair or wool
causes electrons to move from the hair or wool to the balloon
. Because electrons are negatively charged, the balloon acquires a net negative charge. The balloon’s negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon.
What happens when a balloon is rubbed with a cloth?
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 to the stream of water when you hold the charged balloon next to it?
When you bring the charged balloon near to the water it pushes electrons away,
leaving a positively charged area which is attracted to the balloon
. The water coming from the tap is neutral with positive and negative charges. … This positively charged water is attracted to the balloon so the stream is deflected.
How can a balloon become charged and uncharged?
Thus, when two such different substances are brought close to each other (by rubbing, for example), the electrons move from one to the other. The Balloon and Its Invisible Shelf. The balloon becomes
charged when rubbed with wool
. It is attracted to the uncharged wall.
What would happen if you rubbed a balloon with plastic wrap?
The opposite charge is created on the surface of the balloon
when it is rubbed with plastic wrap. The balloon has a positive charge. … The two equal (positive) charges push away from each other. When one balloon is rubbed with wool and one balloon with plastic wrap, the result is opposite charges.
How will 2 positive charges react?
If two positive charges interact,
their forces are directed against each other
. … 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.
What happens if you rub two balloons together?
When you rub both balloons,
both end up with negative charge
. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!
What happens when you rubbed the comb with the wool cloth?
When you rub the comb with the wool,
some of the electrons from the wool are transferred to the comb
. This gives the comb an overall negative charge. … The attraction between the negatively charged comb and the positively charged hydrogen atoms is so strong that you can control the stream by moving the comb.
What will be the result of negatively charged balloon is brought near to the two cans?
When the balloon is brought near the can, something interesting happens –
the electrons move to the side of the can to get as far away from the negatively charged balloon as possible
. This leaves the side of the can nearest the balloon positively charged. … If the can is lying on its side, it will roll away the balloon.
Why does your hair stand up when you rub a balloon on it?
This is because
the rubbing creates a negative charge that is carried by electrons
. The electrons can build up to produce static electricity. … Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.
What happened when you rubbed a balloon on the sweater what happened when that balloon was moved close to the wall?
By rubbing the balloon on a sweater,
you can transfer negative charges onto the surface of the balloon
. If the wall has positive charges on its surface, the opposite charges attract one another, causing the balloon to cling to the wall.
Is water attracted to negative charge?
The slight positive charges on the hydrogen atoms in a water molecule attract the
slight negative charges
on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
Is water attracted to positive charge?
Because water molecules are polarized molecules, the effect is stronger than with dust. … On the right side, the
water stream is attracted towards the positively charged comb
. The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it.
