mohon bantuannya ya kak ^_^ poin nya lumayan kok, tolong kak. mau dikumpul soalnya

MEDAN LISTRIK STATIS
• potensial listrik

Qa = Qb = 10⁻¹⁰ C
V = __?

potensial listrik
V = Σ(k Q / r)


a][ potensial listrik di C
r = AC = BC = 0,2 m

Vc = Va + Vb
Vc = k Qa / r + k Qb / r
Vc = k/r (Qa + Qb)
Vc = 9×10⁹ / 0,2 × (10⁻¹⁰ + 10⁻¹⁰)
Vc = 9×10⁹ / 0,2 × 2×10⁻¹⁰
Vc = 9 V ✓


b][ potensial listrik di D
r = AD = BD = 0,1 m

Vd = Va + Vb
Vd = k Qa / r + k Qb / r
Vd = k/r (Qa + Qb)
Vd = 9×10⁹ / 0,1 × (10⁻¹⁰ + 10⁻¹⁰)
Vd = 9×10⁹ / 0,1 × 2×10⁻¹⁰
Vd = 18 V ✓
