Object A and object B are initially uncharged and are separated by a distance of 1 meter. Suppose 10,000 electrons are removed f

rom object A and placed on object B, creating an attractive force between A and B. An additional 10,000 electrons are removed from A and placed on B and the objects are moved so that the distance between them increases to 2 meters. By what factor does the electric force between them change?

Answer:

1

Explanation:

Let’s denote the charge magnitude for 10,000 electrons as $q$ .

When object A loses charge q, it results in a total charge of $+q$ (since electrons are negatively charged, their loss turns A positively charged). On the other hand, B, which gains q, assumes a charge of $-q$ . They are initially 1 meter apart.

According to Coulomb’s law, the force acting between them is

$F_1 = \dfrac{kq \times q}{1^2}$
