Question

K-9×10степень( 9), r-6 см=6×10степнь -2 ,F =0.2 q =?

Answer 1

K=9 10⁹ Н м²/Кл²            т.к. заряды равны, то з-н Кулона запишем в виде:
r=6 см=6 10⁻² м             F=kq²/r²;   выразим заряд. q²:
F=0,2 H                          q²=Fr²/k; внесем правую и левую часть под корень
q-?               квадратный, получим: q=r√F/k; подставим сюда числа:
                   q=6 10⁻²√0,2/9 10⁹=6 10⁻²√0,02 10⁻⁹=6 10⁻² 10⁻⁴√0,2=2,8 10⁻⁷Кл

Answer 2

I apologize, but the equation you provided doesn't seem to be clear or complete. There are several variables mentioned (K, r, F, q) without any specific context or equation relating them. Additionally, the notation "10степень" is not commonly used.

To assist you better, please provide more information or clarify the equation you are referring to. Include any additional equations or context so that I can understand the problem and provide a meaningful response.
