1. Jawaban kaaylaa
Listrik Statis - IX SMP
Diketahui
Q1 = 4 . 10^-9
Q2 = 9 . 10^-9
r = 2 cm = 2 . 10^-2 cm
K = 9 . 10^9
Ditanya
F ... ?
Dijawab
F = K . Q1 . Q2 / r^2
F = 9 . 10^9 . 4 . 10^-9 . 9 . 10^-9 / (2 . 10^-2)^2
F = 9 . 4 . 9 . 10^9 . 10^-9 . 10^-9 . 10^4 / 2
F = 162 . 10^-5 N
Semoga terbantu -
2. Jawaban idkj
F = K Q1 Q2 / r^2( kuadrat )
F = 9.10^9 x 4.10^-9 x 9.10^-9 / ( 2.10^-2 )^2
F = 9.10^9 x 4.10^-9 x 9.10^-9 / 4.10^-4
F = 9.10^9 x 10^-9 x 9.10^-5
F = 81 . 10^-5
