Question

What do electric forces between charges depend on?

Answer 1

Electrostatic forces between charges depend on the product of
the sizes of the charges, and the distance between them.

We should also mention the item about whether the charges are
both the same sign or opposite signs.  That determines whether
the forces will pull them together or push them apart, which is a
pretty significant item.

Answer 2

Option (C) is correct. The electric force between the two charges depends on the quantity of the charge involved as well as the distance between the charges.

Further Explanation:

When two charges or a system of charges is kept at some distances from one another, the charges experience an electrostatic force of attraction or repulsion depending o the nature of their charge.

The charges experience attraction force if the nature of charges is opposite and they repel if the nature of the two charges is same

This electrostatic force of attraction or repulsion between the two charges is given by the Coulomb’s law. It states that, the force experienced by one charge due to another is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.

It can be expressed mathematically as:

$\begin{aligned}F&\propto\frac{{{q_1}{q_2}}}{{{r^2}}}\hfill\\F&=\frac{1}{{4\pi{\varepsilon _0}}}\frac{{{q_1}{q_2}}}{{{r^2}}}\hfill\\\end{aligned}$  

Therefore, the magnitude of force experienced by the charge depends on the magnitude or the quantity of the charge present as well as the distance between two charges.

Option (C) is correct. The electric force between the two charges depends on the quantity of the charge involved as well as the distance between the charges.
