tolong dong di jawab besok di kumpulin,pliss.

2. F = 14 x 10^-5 N
q = 7 x 10^-9 C
maka medan listriknya adalah
E = F/q
E = (14 x 10^-5)/(7x10^-9)
E = 2 x 10^4 N/C

3. q1 = 6 x 10^-9 C
q2 = 10 x 10^-9 C
r = 3 cm = 0.03 m
k = 9 x 10^9

F = (k q1•q2) / r²
F = (9 x 10^9 x 6 x 10^-9 x 10 x 10^-9) /(0.03)²
F = 6 x 10^-4 N
