Answer 1

`7.2 * 10 {}^(11) newton`

Step-by-step explanation:

`the \: magnitude \: of \: the \: forc \: e \: can \: be \: calculated \: using \: coulombs \: formular \\ f = \frac{k * q1 * q2}{d {}^(2) } \\ f = \frac{9 * 10 {}^(9) * 100 * 20 }{5 {}^(2) } \\ f = \frac{18000 * 10 {}^(9) }{25 } \\ f = (18000000000000)/(25) \\ f = 7.2 * 10 {}^(11) newton`
