dua benda masing masin bermuatan +80uC dan -60uC di pisahkan jarak 120cm hitunglah gaya menarik yang di hasilkan !

80 μC = 80×10-⁶ C
60 μC = 60×10-⁶ C
r = 120 cm = 120×10-² m
k = 9×10⁹

F = k Q1 Q2 / r²
F = 9×10⁹ . 80×10-⁶ . 60×10-⁶ / (120×10-²)²
F = 43200×10-³ / 14400×10-⁴
F = 3×10¹
F = 30 Newton

q1 = + 80 μC = 8 x 10^-5 C
q2 = - 60 μC = 6 x 10^-5 C
R = 120 cm = 12 x 10^-1 m
k = 9 x 10^9 Nm²/C²
Gaya tarik-menarik antar muatan adalah
F = k q1q2/R²
F = 9 x 10^9 (8 x 10^-5)(6x10^-5)/144 x 10^-2
F = 30 N
