Dua buah muatan listrik masing masing +80c dan -40c menimbulkan gaya tarik menarik sebesar 72000 N. Berapakah jarak kedua muatan tersebut?

Soil liquefication occurs in saturated soils when the space b/w individual particles is completely filled with water.This water exerts pressure on the soil particles that influences how tightly the particles themselves are pressed together

loose, saturated soil turns into liquid that can’t support buildings

Soil liquefaction occurs in saturated, loose, unconsolidated soils during earthquakes, where shaking increases pore water pressure, causing the soil to behave like a liquid. This phenomenon is most likely in depths less than 30 feet, particularly in granular materials like sands. The risk to structures is significant, as they can settle or tilt dangerously in liquefied soil.

Jawaban:Soal: Dua buah muatan listrik masing-masing +80 C dan -40 C menimbulkan gaya tarik menarik sebesar 72000 N. Berapakah jarak kedua muatan tersebut? Diketahui: - Muatan 1 (q1) = +80 C- Muatan 2 (q2) = -40 C- Gaya tarik menarik (F) = 72000 N- Konstanta Coulomb (k) ≈ 8.9875 x 10^9 N m²/C² Ditanya: Jarak antara kedua muatan (r) = ? Penyelesaian: Langkah 1: Rumus yang Digunakan Hukum Coulomb: F = k * (|q1 * q2| / r²) Susun ulang untuk mencari r: r = akar((k * |q1 * q2|) / F) Langkah 2: Substitusikan Nilai yang Diketahui r = akar((8.9875 x 10^9) * (|80 * (-40)| / 72000)) r = akar((8.9875 x 10^9) * (3200 / 72000)) r = akar((8.9875 x 10^9) * (0.0444)) r = akar(399049500) r ≈ 19976.22 meter Jawaban: Jarak antara kedua muatan tersebut adalah sekitar 19976.22 meter.
