Here's why:
* Inverse Square Law: The electric field strength follows an inverse square law. This means that the strength of the field is proportional to the inverse of the square of the distance from the charge.
* Formula: The electric field (E) due to a point charge (q) at a distance (r) is given by:
E = k * q / r²
where k is Coulomb's constant.
* Explanation: As you get closer to the charge (r decreases), the denominator in the formula gets smaller. This results in a larger value for the electric field (E).
In simpler terms: Imagine the electric field as lines radiating outwards from the charge. As you move closer to the charge, these lines become more concentrated, meaning the field strength is stronger.
