gaya total yang dialami muatan q1 sebesar 6,759 N dengan arah ke kanan (bertanda positif).space

Pembahasan

Gaya tarik-menarik atau gaya tolak-menolak antara dua muatan listrik di sebut gaya Coulomb. Besar gaya Coulomb (F) dirumuskan sebagai:

F equals k fraction numerator q subscript 1 q subscript 2 over denominator r squared end fraction

dengan,

k = konstanta open parentheses 9 cross times 10 to the power of 9 space Nm squared divided by straight C squared close parentheses

q = muatan listrik (C)

r = jarak dua muatan(m)

Pada Soal Ini

Diketahui:

q1 = 3 μC = 3 × 10-6 C

q2 = -6 μC = -6 × 10-6 C

q3 = 2 μC = 2 × 10-6 C

r12 = 15 cm = 0,15 m

r23 = 20 cm = 0,2 m

Ditanya: F1 = ...?

Jawab:

Ilustrasi posisi ketiga muatan.dan gaya listrik yang bekerja pada q1.

Kita sepakati vektor gaya ke arah kanan (F12) bertanda positif (+) dan vektor gaya listrik ke arah kiri (F13) bertanda negatif (-). Maka gaya total yang dialami oleh muatan q1 adalah
