poin menarik jawab ya.. (jawab asal, report)
Jawaban:
A. 4 cm
Penjelasan dengan langkah-langkah:
Hukum Coulomb
[tex] \sf F = k \times \frac{q_1 . q_2}{r^{2}}[/tex]
[tex] \sf135=( 9 \times {10}^{9} ) \times \frac{(6 \times {10}^{ - 6}) . (4 \times {10 }^{ - 6}) }{r^{2}}[/tex]
[tex] \sf 135 = 9 \times {10}^{9} \frac{24 \times {10}^{ - 12} }{ {r}^{2} } [/tex]
[tex] \sf135 {r}^{2} = 2.16 \times {10}^{ - 1} [/tex]
[tex] \sf {r}^{2} = \frac{1}{625} [/tex]
[tex] \sf r = \frac{1}{25} = 0.04 \:m[/tex]
[tex] \sf r = \boxed{ \bold{ \red{4 \: cm}}}[/tex]
Jawabannya adalah A (4 cm)
