Verified answer
Diketahui :Q1 = 12 micro C = 12 10^-6 C
Q2 = 15 micro C = 15 10^-6 C
k = 9 10^9 Nm^2/C^2
F = 2 N
Ditanya jarak (r).
Pembahasan.
Persamaan gaya listrik
F = k Q1 Q2 / r^2
r^2 = k Q1 Q2 / F
r^2 = 2m9 10^9 Nm^2/C^2 12 10^-6 C 15 10^-6 C / 2 N
r^2 = 162/2 10^-2 m^2
r^2 = 81 10^-2 m^2
r = akar ( 81 10^-2 m^2)
r = 9 10^-1 m
r = 0,9 m
Kesimpulannya.
Jarak antara muatan tersebut adalah 9 10^-1 m.
