q2 = 4 × 10⁻⁹ C
r = 2 cm = 2 × 10⁻² m
k = 9 × 10⁹ Nm²/C²
F = k . q1 . q2/r²
F = (9 × 10⁹) . (8 × 10⁻⁹) . (4 × 10⁻⁹)/(2 × 10⁻²)²
F = 288 × 10⁻⁹/4 × 10⁻⁴
F = 72 × 10⁻⁹⁻⁽⁻⁴⁾
F = 72 × 10⁻⁵ = 7,2 × 10⁻⁴ N

F = 9.10⁹. 8.10⁻⁹. 4.10⁻⁹ / ( 2.10⁻² )²
F = 9.10⁹. 8.10⁻⁹. 4.10⁻⁹ / 4.10⁻⁴
F = 9.10⁹. 8.10⁻⁹.10⁻⁹ / 10⁻⁴
F = 9.10⁹. 8.10⁻⁹.10⁻⁹. 10⁴
F = 72.10⁻⁹. 10⁴
F = 72 x 10⁻⁵
F = 7,2 x 10⁻⁴ N
