If the distance between two charges is doubled, what happens to the Coulomb force?

If the distance between two charges is doubled, the Coulomb force becomes:

Two equally charged small balls placed at a fixed distance experience a force 'F'. A similar uncharged ball after touching one of them is placed at the middle point between the two balls. The force experienced by this ball is ______.

Two point charges \( +2 \, \mu\text{C} \) and \( -3 \, \mu\text{C} \) are placed 10 cm apart in vacuum. What is the electrostatic force between them?

Two point charges $+3 \; \mu\text{C}$ and $+8 \; \mu\text{C}$ repel each other with a force of $40 \text{ N}$. If a charge of $-5 \; \mu\text{C}$ is added to each of them, then the force between them will become

Two positive ions, each carrying a charge $q$ are separated by a distance $d$. If $F$ is the force of repulsion between the ions, the number of electrons missing from each ion will be ($\varepsilon_0$ = permittivity of free space, $e$ = charge on an electron)

'F' is the force between the two identical charged particles placed at a distance 'Y' from each other. If the distance between the charges is reduced to half the previous distance then force between them becomes
