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

Click For Summary
SUMMARY

The discussion centers on a physics problem involving two neutral spherical objects that acquire negative charges due to the addition of electrons, resulting in an electrostatic force of 5.75 x 10-3 N between them. The distance separating the objects is 2.5 x 10-3 m. Participants clarify that Coulomb's Law, which relates electrostatic force (F) to charge (q) and distance (d), is essential for solving the problem. The correct application of Coulomb's Law will yield the number of electrons required to produce the specified charge on one object.

PREREQUISITES
  • Coulomb's Law
  • Understanding of electrostatic force
  • Basic knowledge of charge and electrons
  • Familiarity with the formula F = k * (q1 * q2) / d2
NEXT STEPS
  • Calculate the charge on one object using Coulomb's Law
  • Determine the number of electrons corresponding to the calculated charge
  • Explore the concept of electrostatic force in greater detail
  • Review the principles of electric charge and conservation of charge
USEFUL FOR

Students studying physics, particularly those focusing on electrostatics, as well as educators seeking to clarify concepts related to charge and electrostatic forces.

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?
