How does the electric potential energy between two positively charged particles change if the distance between them is reduced by a factor of 3?

The electric potential energy will increase by a factor of 3

Electric charge consists of two types i.e. positively electric charge and negatively electric charge.

There was a famous scientist who investigated about this charges. His name is Coulomb and succeeded in formulating the force of attraction or repulsion between two charges i.e. :

F = electric force (N)

k = electric constant (N m² / C²)

q = electric charge (C)

r = distance between charges (m)

The value of k in a vacuum = 9 x 10⁹ (N m² / C²)

Let's tackle the problem now !

Given:

R₂ = ⅓ R₁

Unknown:

Ep₂ = ?

Solution:

This problem is about Electrical Potential Energy.

We will compare the electric potential energy from the two conditions above.

From the results above, we can conclude that the electric potential energy will increase by a factor of 3
