Dik : q1 = -32 MC = -3.10^-5 C q2 = 20 MC = 2.10^-5 C r = 14 cm = 0.14 m dit : F = ...? peny : F = k. q1.q2/r^2 F = 9.10^9 . -3.10^-5 . 2.10^-5/ (0,14)^2 F = -54.10-1 / 0.0196 F = -2755.1 × 10^-1 F = -275,51 N
q2 = 20 MC = 2.10^-5 C
r = 14 cm = 0.14 m
dit : F = ...?
peny :
F = k. q1.q2/r^2
F = 9.10^9 . -3.10^-5 . 2.10^-5/ (0,14)^2
F = -54.10-1 / 0.0196
F = -2755.1 × 10^-1
F = -275,51 N
