When two identical conducting spheres are brought together to touch, they share the charge evenly between them. The change in the repulsive force between the spheres after and before they are brought into contact can be calculated using Coulomb's law. The result does not depend on the initial and final distance between the charges.
When two identical conducting spheres are brought together to touch, they share the charge evenly between them. The total charge is spread out across the whole surface of the spheres. When they are separated again, each sphere is left with half of the original charge.
The change in the repulsive force between the spheres after and before they are brought into contact can be calculated using Coulomb's law. The force between two charged spheres is given by the formula F = k * (Q1 * Q2) / r^2, where k is the electrostatic constant, Q1 and Q2 are the charges on the spheres, and r is the distance between the spheres.
The result does not depend on the initial and final distance between the charges. The change in the repulsive force is only determined by the change in charge on the spheres.
