Here's why:
* Coulomb's Law: The force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically:
F = k * (q1 * q2) / r²
where:
* F is the electric force
* k is Coulomb's constant
* q1 and q2 are the magnitudes of the charges
* r is the distance between the charges
* Zero Distance: As the distance (r) approaches zero, the denominator of the equation approaches zero. Dividing by zero results in an infinite value.
Important Note: In reality, charges cannot be brought to a distance of zero. The concept of point charges is an idealized model, and real charges have finite size.
