Dua muatan listrik masing masing sebesar 12C-4C diletakan pada jarak 40 cm antara satu sama lain. jika jarak K= 9X10^9NM^2/C^2, hitunglah gaya tarik antara kedua muatan itu

Diketahui : q1 = 12 c q2 = 4 c r = 40 cm = 0,4 m = 4.10^-1 Dit = F..... F = k.q1.q2/r^2 F = 9.10^9.12.4/(4.10^-1)^2 F = 9.12.4.10^9/4^2.10^-2 F = 432.10^9/16.10^-2 =27.10^9/10^-2 =27.10^9.10^2 =27.10^11 c
q2 = 4 c
r = 40 cm = 0,4 m = 4.10^-1
Dit = F.....
F = k.q1.q2/r^2
F = 9.10^9.12.4/(4.10^-1)^2
F = 9.12.4.10^9/4^2.10^-2
F = 432.10^9/16.10^-2
=27.10^9/10^-2
=27.10^9.10^2
=27.10^11 c
