Diket: q₁ = 4.10⁻⁹ q₂ = 9.10⁻⁹ r = 2cm = 2.10⁻² m k = 9.10⁹ Nm²/C² Dit: F....? F = kq₁q₂/r² F = 9.10⁹ x 4.10⁻⁹ x 9.10⁻⁹/(2.10⁻²)² F = 9.10⁹ x 4.10⁻⁹ x 9.10⁻⁹/4.10⁻⁴ F = 81.10⁻⁹/1.10⁻⁴ F = 81.10⁻⁵ N F = 8,1.10⁻⁶ N
q₁ = 4.10⁻⁹
q₂ = 9.10⁻⁹
r = 2cm = 2.10⁻² m
k = 9.10⁹ Nm²/C²
Dit: F....?
F = kq₁q₂/r²
F = 9.10⁹ x 4.10⁻⁹ x 9.10⁻⁹/(2.10⁻²)²
F = 9.10⁹ x 4.10⁻⁹ x 9.10⁻⁹/4.10⁻⁴
F = 81.10⁻⁹/1.10⁻⁴
F = 81.10⁻⁵ N
F = 8,1.10⁻⁶ N
