So, what changed?Dezzi said:
I guess the charges get equalised. So, you've worked out that average charge: ##2.5 nC##, which looks right.PeroK said:
An electric field is a region around a charged object where other charged objects experience a force. It is created by the presence of a charged object and can be either attractive or repulsive depending on the charge of the objects involved.
The repulsive force between two charged spheres is a result of the electric field created by the charges on the spheres. The electric field exerts a force on the charges, causing them to repel each other.
The strength of the repulsive force between two charged spheres is affected by the magnitude of the charges on the spheres, the distance between the spheres, and the medium in which the spheres are located. The force increases with the magnitude of the charges and decreases with the distance between the spheres. The medium can also affect the force through its dielectric constant.
The repulsive force between two charged spheres can be calculated using Coulomb's law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the spheres. The formula is F = (k * q1 * q2) / r2, where k is the Coulomb's constant, q1 and q2 are the charges on the spheres, and r is the distance between them.
Yes, the repulsive force between two charged spheres can be completely eliminated if the charges on the spheres are equal in magnitude and opposite in sign. In this case, the electric field between the spheres will be zero, and there will be no force of repulsion. This is known as a neutralization reaction.
