1. Dik : q₁ = 6 . 10⁻⁹ C
q₂ = 8 . 10⁻⁹ C
K = 9 . 10⁹ Nm²/C²
r = 4 cm
Dit : Fc = ….? N
Penyelesaian :
Fc = K . q₁.q₂/r²
Fc = 9.10⁹ . 6.10⁻⁹ . 8.10⁻⁹/(4.10⁻²)²
= 9.10⁹ . 48.10⁻⁹ ⁺ ⁽⁻⁹⁾/(4².10⁻⁴)
= 9.10⁹ . 48.10⁻¹⁸/16.10⁻⁴
= 432 . 10⁹ ⁺ ⁽⁻¹⁸⁾/16 . 10⁻⁴
= 432 . 10⁻⁹/16 . 10⁻⁴
= 432/16 . 10⁻⁹ ⁻ ⁽⁻⁴⁾
= 27 . 10⁻⁹ ⁺ ⁴
= 27 . 10⁻⁵ N
