oblicz sile jaka dziala na 2 ladunki q1=20 uc q2=80uc ktore sa oddalone od siebie o 20 cm

q₁ = 20 μC = 20*10⁻⁶ C q₂ = 89 μC = 80 *10⁻⁶ C r = 20 cm = 0,2 m k = 9 *10⁹ N * m² / C² F = ? [latex]F = frac{kq_1q_2}{r^2} [/latex] [latex]F = frac{9 *10^9 frac{N*m^2}{C^2} *20 *10 ^{-6}C * 80 *10 ^{-6} C }{(0,2 m )^2} [/latex] [latex]F = frac{14400 *10 ^{-3} N*m^2}{4 *10 ^{-2} m^2} F = 3600 *10 ^{-1} N = 3,6 *10^3 *10 ^{-1} = 3,6 *10^2 N[/latex]
