What is the formula for the electric field (E) due to a point charge (Q) at a distance (r)?

Step 1: Understand that a point charge is an object with an electric charge concentrated at a single point.
Step 2: Know that the electric field (E) is a way to describe how a charge affects the space around it.
Step 3: Recognize that the distance (r) is how far you are from the point charge.
Step 4: Learn that Coulomb's constant (k) is a number that helps us calculate the strength of the electric field.
Step 5: The formula for the electric field (E) due to a point charge (Q) at a distance (r) is E = k * Q / r^2.
Step 6: In this formula, 'k' is a constant, 'Q' is the amount of charge, and 'r^2' means you square the distance.
