bantu dong mau dikumpulin nih
Penjelasan:
q₁ = 4.10⁻⁹ ΞΌC
q₂ = 9.10⁻⁹ ΞΌC
r = 2 Cm = 0,02 m = 2.10⁻²
k = 9.10⁹ Nm²/C²
Gaya Coulomb (F) :
[tex]F = k \frac{q _1.q_2}{ {r}^{2} } [/tex]
[tex]F = 9. {10}^{9} \frac{4.{10}^{ - 9}·9 {10}^{ - 9} }{2. {10}^{ - 2} } [/tex]
[tex]F = \frac{9. \cancel4.9· {10}^{9 - 9 - 9} }{ \cancel4. {10}^{ - 4} } [/tex]
[tex]F = \frac{81. {10}^{ - 9} }{ {10}^{ - 4} } [/tex]
[tex]F = 81. {10}^{ - 5} [/tex]
[tex]F = \bold{8,1 \times {10}^{ - 4} \: N}[/tex]
Jawaban:
81 × 10^-5 N
