Question

duas cargas elétricas iguais de 2? alguém sabe?

Answer 1

Boa noite, vamos fazer essa questão, usando a lei de Coulomb.

Q1 = Q2 =  2 · 10⁻⁶ C

K₀ = 9.10⁹ N m²/C²

F = 0,1 N

d = ??

aplicando.

F =  \frac{K_o.Q^2}{d^2} \\\\
0,1*d^2=9.10^9.(2.10^{-6})^2 \\\\
 0,1*d^2=9.10^9.4.10^{-12}\\\\
d^2= \frac{36.10^{-3}}{1.10^{-1}} \\\\
d^2=36.10^{-2}\\\\
d= \sqrt{36.10^{-2}} \\\\
d= 6.10^{-1}\\\\
\boxed{\boxed{d=0,6~m}}

letra A) 0,6 m
