You need to know the distance between centers of objects to calculate the force. If 1.9 cm is the distance between the skins of the balloons, then you'd need to know the radii of the balloons to do the problem.

If the 1.9 cm is meant to be the distance between their centers, then these are really tiny balloons, but let's go with that, since it's all we can do.

Look up the formula for Coulomb's Law, and the value of k in that law. Use the values in your problem to solve for F. Don't forget to convert 1.9 cm to meters first.

Do the balloons have the same charges. Each balloon is pushing the other away?

The balloons likely have the same charge, causing them to repel each other due to the electrostatic force. This repulsion is a result of like charges (positive or negative) creating a force that pushes the balloons apart.


If the leaves of and electroscope spread apart it indicates that?

the electroscope has acquired a net charge. This charge can be positive or negative, depending on the nature of the object that interacted with the electroscope. The repulsion between the like charges on the leaves causes them to spread apart, indicating the presence of a charge.


What is the force between two balloons with a negative charge of 1.6 x C if the balloons are cm apart?

The force between two charged objects can be calculated using Coulomb's law, which states: F = k * (|q1 * q2|) / r^2, where k is the electrostatic constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the objects (1.6 x 10^-9 C in this case), and r is the distance between the objects (in meters, so convert cm to meters). Plugging in these values will give you the force between the two balloons.


What happens when you blow air between 2 balloons of nearly equal size hanging on a stick?

When you blow air between two balloons of nearly equal size hanging on a stick, the balloons will move away from each other due to the air pressure pushing them apart. This occurs because the air flow creates a region of higher pressure between the balloons, causing them to repel each other.


What will happen when two balloons are brought together right after they are rubbed on a piece of wool?

When you rub one balloon with wool, and then rub another balloon with wool, we can safely assume that both balloons acquire the same kind of charge. So when you try to bring them together, they'll repel each other (push apart).

What is the force between two balloons with a negative charge of 1.6 x10 -10C if the balloons are 5.0 cm apart?

The force between two charges can be calculated using Coulomb's Law: F = k * (q1 * q2) / r^2, where k is the Coulomb's constant (8.99 x 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between the charges. Plugging in the values, we get F = (8.99 x 10^9) * (1.6 x 10^-10)^2 / (0.05)^2, which gives F = 1.4064 x 10^-4 N.


Can plasma have a negative charge?

Plasma can't have a net overall charge, either positive or negative. If it did, it would blow itself apart, because the electromagnetic force is many orders of magnitude greater than the gravitational force.


Where the net electric force is zero between two point charge that apart?

The net electric force between two point charges is zero at the point where the electric field due to one charge cancels out the electric field due to the other charge. This occurs along the line connecting the two charges at a point where the electric field vectors due to each charge are equal in magnitude but opposite in direction.


If you blow a stream of air between two balloons that are next to each other the balloons?

They draw closer together. The high speed air causes a partial vacuum, the relative pressure on the outside of the balloons pushes them closer together. This is principle by which an aeroplane wing works. It is called the Bernoulli principle.


What does the Electric Force between two charged objects depend on A Their masses and their separation B Their speeds C their charge and their separation D their masses and their charge?

Well, an electric force can be attractive or repulsive and it is the STRONGEST force in nature. And to feel this force, small changes might be involved.So, the question is: The Electric Force between two charged objects depends on which of the following?A) Their masses and their separationB) Their speedsC) their charge and their separationD) their masses and their chargeAnswer: C) Their charge and their separation.Why? Because the force between electric charges depends on the distance between charges (the force decreases as the charges get farther apart) and it depends on the force the electric charges exert on each other. And negative charge and positive charge do attract but positive and positive charge don't attract and negative and negative don't attract.


What is the difference between organize and disorganize?

The prefix "dis" means "apart, asunder or having a negative or reversing force." Disorganize, therefore, is the negative of organize and means the opposite.


What happens to statically charged objects as they move apart?

Statically charged objects will experience an attractive or repulsive force that causes them to move apart. This is due to the electrostatic force between the charges on the objects. The force is determined by the magnitude of the charges and the distance between them, following Coulomb's law.
