2 neutral objects produce a charge, how many electrons added?

In summary, two small spherical objects with a distance of 2.5 x 10-3 m between them acquire the same negative charge due to the addition of electrons. Each object experiences an electrostatic force with a magnitude of 5.75 x 10-3 N. To calculate the charge on one of the objects, Coulomb's law can be used, which involves the distance between the objects and the electrostatic force. The number of electrons needed to produce the charge can be calculated using this formula.

Homework Statement


Two spherical objects are separated by a distance of 2.5 x 10-3 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result each object experiences an electrostatic force that has a magnitude of 5.75 x 10-3 N. How many electrons did it take to produce the charge on one of the objects.

The Attempt at a Solution


The lecture notes imply columb's law is involved, distance is d obviously but electrostatic force isn't part of columb's law so do i need to ue another formula? The hard bit in these q's is just figuring out which formula to use, then you just slot in the values so does anyone know which rule(s) to apply here?

What does "F" stand for in Coulomb's law?

Related to 2 neutral objects produce a charge, how many electrons added?

1. How do neutral objects produce a charge?

When two neutral objects come into contact with each other, the electrons from one object can transfer to the other object, causing an imbalance in the number of protons and electrons. This imbalance creates a net charge on the objects, making them either positively or negatively charged.

2. Can neutral objects produce a charge on their own?

No, neutral objects cannot produce a charge on their own. They require contact with another object to transfer electrons and create a charge.

3. How many electrons are added when two neutral objects produce a charge?

The number of electrons added depends on the size and type of objects involved. Generally, the larger the objects, the more electrons will be transferred and the greater the charge produced.

4. How does the type of material affect the transfer of electrons?

The type of material can affect the transfer of electrons. Some materials, such as metals, are good conductors and allow electrons to flow easily, while others, such as insulators, do not allow electrons to move as freely.

5. What happens when two objects with the same charge come into contact?

If two objects with the same charge come into contact, they will repel each other due to the like charges. This is because objects with the same charge have an excess of either positive or negative charges, causing them to push away from each other.
