Respuesta:
[tex]F_{E} = 210N[/tex]
Explicación:
Ley de Coulomb.
Datos:
[tex]q_{1}[/tex] = 7μC ≡ [tex]7x10^{-6}[/tex] C [tex]q_{2}[/tex] = 3μC ≡ [tex]3 x 10^{- 6}[/tex]C r = 3cm ≡ [tex]3x10^{-2}[/tex]m
[tex]K = 9x10^{9} N*m^{2} /C^{2}[/tex]
Ecuacion:
[tex]F_{E} = K*\frac{q_{1} *q_{2} }{r^{2} }[/tex] Remplazando valores conocidos y realizando las operaciones indicadas tenemos.
[tex]F_{E} = 9x10^{9} N*m^{2} /C^{2} * \frac{7x10^{-6}C *3x10^{-6} C}{(3x10^{-2} m)^{2} } \\F_{E} = 9x10^{9} N*m^{2} /C^{2}*\frac{21x10^{-12} C^{2} }{9 x10^{-4} m^{2} } \\F_{E} = \frac{189x10^{-3} N*m^{2}}{9 x10^{-4} m^{2}} \\\\F_{E} = 21x10^{1} N\\F_{E} = 210N[/tex]
