Dua muatan sejenis besarnya +4 x 10pangkatmin6 C dan +3 x 10pangkatmin6 C terpisah pada jarak 2cm. Jika konstanta Coulomb k = 9 x 10pangkat9 Nmpangkat2/Cpangkat2 , hitung gaya elektrostatisnya !

Diket: q1 = + 4.10^-6 C q2 = + 3.10^-6 C r = 2 cm = 2.10^-2 m k = 9.10^9 Nm²/C² Dit: F....? F = k.q1.q2/r² F = 9.10^9 x 4.10^-6 x 3.10^-6 / (2.10^-2)² F = 9.10^9 x 4.10^-6 x 3.10^-6 / 4.10^-4 F = 9.10^9 x 10^-2 x 3.10^-6 F = 270 N
q1 = + 4.10^-6 C
q2 = + 3.10^-6 C
r = 2 cm = 2.10^-2 m
k = 9.10^9 Nm²/C²
Dit: F....?
F = k.q1.q2/r²
F = 9.10^9 x 4.10^-6 x 3.10^-6 / (2.10^-2)²
F = 9.10^9 x 4.10^-6 x 3.10^-6 / 4.10^-4
F = 9.10^9 x 10^-2 x 3.10^-6
F = 270 N
