Penjelasan:
diketahui :
qA = 36 mC = 36 × 10-³ C
qB = -16 mC = -16 × 10-³ C
r = 10 cm
k = 9 × 10⁹ Nm²/C²
ditanya :
jarak muatan A dan B berturut turut?
Jawab :
EA = EB
k. qA/r² = k. qB/r²
qA/r² = qB/r²
36.10-³/x² = 16.10-³/(10 + x)²
(10 + x)²/x² = 16/36
(10 + x)/x = 4/6
4x = 60 + 6x
-2x = 60
x = 60/-2
x = -30 cm
jarak xa :
= 10 - 30
= -20 cm
