Penjelasan:

$f = k frac{q1q2}{ {r}^{2} } \ f = 9 times {10}^{9} frac{6 times {10}^{ - 6} times 6 times {10}^{ - 6} }{ {(3 times {10}^{ - 3}) }^{2} } \ f = 9 times {10}^{9} frac{36 times {10}^{ - 12} }{9 times {10}^{ - 6} } \ f = 9 times {10}^{9} times frac{1}{9} times {10}^{6} times 36 times {10}^{ - 12} \ f = 36 times {10}^{3} \ f = 3.6 times {10}^{4} n$

10.

$f = k frac{q1q2}{ {r}^{2} } \ f = 9 times {10}^{9} frac{5 times 4}{ {3}^{2} } \ f = {10}^{9} times 20 \ f = 2 times {10}^{10} n$

$f = k frac{q1q2}{ {r}^{2} } \ f = 9 times {10}^{9} frac{3 times {10}^{ - 6} times 1 times {10}^{ - 6} }{(30 times {10}^{ - 2} ) {}^{2} } \ f = 9 times {10}^{9} frac{3times {10}^{ - 12} }{9 00times {10}^{ - 4} } \ f =9 times {10}^{9} times frac{1}{900} times {10}^{4} times 3 times {10}^{ - 12} \ = frac{1}{100} times {10}^{1} times 3 \ = frac{30}{100} \ = 0.3 : n$
