Question

решите таблицу пожалуйста.

Answer 1

F = k*q1*q2/(E*r^2)
k = 9*10^9
1. F = 9*10^9*6.1*10^-6*4.1*10^-6/(1*36) =9*6.1*4.1*10^-3/36 = 0.006 Н
2. q1 = F*E*r^2/(k*q2) = 1.5*10^-6*2*25/(9*10^9*3.1*10^-6) = 1.5*50*10^-9/(9*3.1) = 2.69*10^-9 Кл
3. q2 = F*E*r^2/(k*q1) = 2.5*10^-5*4*16/(9*10^9*5.1*10^-6) = 160*10^-8/(9*5.1) = 3.49*10^-8 Кл
4. r = sqrt(k*q1*q2/(E*F)) = sqrt(9*10^9*4.1*10^-6*2.1*10^-6/(6*3.5*10^-4)) = sqrt(9*4.1*10*2.1/(6*3.5)) = 17.6 м
5. E = k*q1*q2/(r^2*F) = 9*10^9*3.1*10^-3*1.1*10^-3/(9*0.5*10^3) = 3.1*1.1/0.5 = 6.82
