5.
m1v1 + m2v2 = m1v1' + m2v2'
0,05 x 800 + 0 = 0,05 x 100 + 250 x v2'
v2' = 0,14 m/s
6.
F = k Q1 Q2 / r²
B ditarik A ke kiri
B ditarik C ke kanan
Fb = Fc - Fa
Fb = k Qb Qc/r² - k Qb Qa/r²
Fb = k Qb/r² (Qc - Qa)
Fb = 9x10⁹ x 1x10⁻⁶ / 1² x 2x10⁻⁶
Fb = 0,018 N

R3 R4 paralel
1/R34 = 1/3 + 1/6 = 2/6 + 1/6 = 3/6
R34 = 6/3 = 2
R34 R2 diseri
R342 = 2+4 = 6
R5 R342 diparalel
1/R3425 = 1/6 + 1/12 = 2/12 + 1/12 = 3/12
R3425 = 12/3 = 4
R3425 R1 diseri
R34251 = 2+4 = 6
a. Rac = R34251 = 6
b. i =V/R
R = Rac + r = 6 + 0,5 = 6,5
i = 26/6,5 = 4 A
c. Vab = i x R1 = 4 x 2 = 8 volt
Vbc = i x R3425 = 4 x 4 = 16 volt
Vac = i x Rac = 4 x 6 = 24 volt
d.i2 = Vbc/R342 = 16/6 = 2,67 A
i5 = Vbc/R5 = 16/12 = 1,33 A
