The force between two uniformly charged spheres that are firmly fastened depends on the charge of each sphere, the distance between them, and the permittivity of the medium between them. This force 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 them.
The force between two uniformly charged spheres is inversely proportional to the square of the distance between them. This means that as the distance between the spheres increases, the force decreases. Similarly, as the distance decreases, the force increases.
Yes, the charge of the spheres directly affects the force between them. The greater the charges on the spheres, the greater the force between them. Similarly, if the charges have opposite signs, the force will be attractive, while if they have the same sign, the force will be repulsive.
The permittivity of the medium between the spheres is a measure of the medium's ability to store an electric field. It is denoted by the symbol ε and is typically measured in units of farads per meter (F/m). The permittivity of a vacuum is approximately 8.85 x 10^-12 F/m.
No, Coulomb's law can only be used to calculate the force between two uniformly charged spheres. If the charge distribution on the spheres is non-uniform, a different method, such as integration, must be used to calculate the force between them.
