What is the strength of the electric field 0 point 0 2 0 m from a 12 mu cap c charge? (Use k is equal to 8 point 9 9 times 10 to the 9th power cap n the fraction with numerator m squared and denominator cap c squared )

For a point charge, the electric field strength is E = kq/r². Convert 12 μC to 12 × 10⁻⁶ C and use r = 0.020 m: E = (8.99 × 10⁹)(12 × 10⁻⁶)/(0.020)² ≈ 2.7 × 10⁸ N/C. Therefore, the correct choice is A, 2.7 × 10⁸ N/C.
