Question

Bantu jawab ya kawan

Answer 1

Jawaban:

1. F = 180 N

2. EB = 150 N/C

3. QB = 8.10⁻¹² C

Penjelasan:

1. Gaya Coulomb

F = k.q1.q2/r² = 9.10⁹. 2.10⁻⁶. 4.10⁻⁶/(2.10⁻²)²

F = 180 N

2. Medan listrik EB yang dirasakan muatan A disebabkan oleh muatan B yaitu QB.

EB = k.QB/r²  --> kuat medan di A disebabkan B

F = k.QA.QB/r²  = QA. EB

EB = F/QA = 3.10⁻⁴ / 2.10⁻⁶

EB = 150 N/C

3. EB = k.QB/r²  --> kuat medan di A disebabkan B

QB = EB. r²/k = 80. (3.10⁻²)²/(9.10⁹)

QB = 8.10⁻¹² C
