2 buah muatan masing masing 8 mikro coulumb dan 7 mikro coulumb terpisah sejauh 2 cm,jika k=9*10^9.hitunglah a.gaya coulumb antara kedua muatan. b.kuat medan li

q₁ = 8 μC = 8×10⁻⁶ C
q₂ = 7 μC = 7×10⁻⁶ C
r = 2 cm = 2×10⁻² m
k = 9×10⁹ N/
a.) F = ...?
b.) E di 7 μC = ...?

a.)
[tex]F = k \frac{q_{1} q_{2}}{r^{2}} \\ F = 9 \times 10^{9} \frac{ (8 \times 10^{-6}) (7 \times 10^{-6})}{ (2 \times 10^{-2})^{2}} \\ F = 126 \times 10^{-1} N = 12,6 N[/tex]

b.)
[tex]E = \frac{F}{q} \\ E = \frac{12,6}{7 \times 10^{-6}} \\ E = 1,8 \times 10^{6} N/[/tex]
