What is the electric field due to a point charge of +1μC at a distance of 1m?

Step 1: Identify the formula for the electric field (E) due to a point charge, which is E = k * |q| / r^2.
Step 2: Determine the values needed for the formula: k (Coulomb's constant) is approximately 9 × 10^9 N m²/C², |q| (the charge) is +1μC, which is 1 × 10^-6 C, and r (the distance) is 1m.
Step 3: Substitute the values into the formula: E = (9 × 10^9) * (1 × 10^-6) / (1)^2.
Step 4: Calculate the numerator: (9 × 10^9) * (1 × 10^-6) = 9 × 10^3.
Step 5: Since r^2 is (1)^2 = 1, the denominator is 1.
Step 6: Divide the numerator by the denominator: E = 9 × 10^3 / 1 = 9 × 10^6 N/C.
