jdi bsar muatan listrikny adalah16,6
maaf salah..
F = 100 N
Q1 = Q2
r = 6 cm = 6 x 10^-2 m
k = 9x10^9 Nm^2/c^2
Q1 & Q2 = ...
jwb
F = k.Q1.Q2/r^2
F.r^2/k = Q1.Q2
F.r^2/k = Q1.Q1
100.(6.10^-2)^2 / 9.10^9 = Q1^2
100.36.10^-4 / 9.10^9 = Q1^2
100.4.10^-4 / 10^9 = Q1^2
400.10^-4.10^-9 = Q1^2
400.10^(-4+(-9)) = Q1^2
400.10^-13 = Q1^2
4.10^-11 = Q1^2
√(4.10^-11) = Q1
2.10^-5.√(10^-1) = Q1
jadi besar muatan listrik tsb masing masing 2.10^-5.√(10^-1) C
maaf klo rumit ^_^
