Fisika please ada yang bisa bantu jawab ga ​

please ada yang bisa bantu jawab ga ​

Diketahui:

Q1 = 3 μC = 3 x 10^-6 C

Q2 = 6 μC = 6 X 10^-6 C

Q3 = 9 μC = 9 x 10^-6 C

R21 = 4 m

R23 = 5 m

k = 9 x 10^9 Nm^2/C^2

Ditanyakan:

F2?

Pembahasan:

1. Gaya pada muatan 2 akibat muatan 1

F21 = (k x Q1 x Q2) / (R21)^2

F21 = (9 x 10^9 x 3 x 10^-6 x 6 x 10^-6) / (4)^2

F21 = (27 x 10^3 x 6 x 10^-6) / (16)

F21 = (162 x 10^-3) / (16)

F21 = 10,125 x 10^-3 N

2. Gaya pada muatan 2 akibat muatan 3

F23 = (k x Q1 x Q3) / (R23)^2

F23 = (9 x 10^9 x 3 x 10^-6 x 9 x 10^-6) / (5)^2

F23 = (27 x 10^3 x 9 x 10^-6) / (25)

F23 = (243 x 10^-3) / (25)

F23 = 9,72 x 10^-3 N

3. Gaya pada muatan 2 akibat muatan 1 dan 3

F2 = F21 - F23

F2 = (10,125 x 10^-3) - (9,72 x 10^-3)

F2 = 0,405 x 10^-3 N

F2 = 4,05 x 10^-4 N
