Jawaban:
[tex]9 \times {10}^{ - 1} = \frac{9. {10}^{9} \times 4. {10}^{ - 6} \times 1.{10}^{ - 6} }{ {r}^{2} } [/tex]
[tex]9. {10}^{ - 1} = \frac{36. {10}^{9 + ( - 6) + ( - 6)} }{ {r}^{2} } [/tex]
[tex]9. {10}^{ - 1} = \frac{36. {10}^{9 - 6 - 6} }{ {r}^{2} } [/tex]
[tex]9. {10}^{ - 1} = \frac{36. {10}^{ - 3} }{ {r}^{2} } [/tex]
[tex] \frac{36. {10}^{ - 3} }{9. {10}^{ - 1} } = {r}^{2} [/tex]
[tex]4. {10}^{( - 3) - ( - 1)} = {r}^{2} [/tex]
[tex]4. {10}^{ - 3 + 1} = {r}^{2} [/tex]
[tex]4. {10}^{ - 2} = {r}^{2} [/tex]
[tex] \sqrt{4. {10}^{ - 2} } = r[/tex]
[tex]2. {10}^{ - 1} = r[/tex]
[tex]0.2 \: m = r[/tex]
