Question
Does the force on a charge due to another charge depend on the charges present nearby?
✓

Answer

Coulomb's Law states that the force between two charged particle is given by,

$\text{F}=\frac{\text{q}_1\text{q}_2}{4\pi\in_0\text{r}^2}$

Where,

q1 and q2 are the charges on the charged particles .

r = separation  between the charged particles.

$\in_0$ = parmittivity of free space.

According to the Law of Superposition, the electrostatic force between two charged particles are unaffected due to the presence of other charges.
