Odpowiedź:
F= 1/2q1* 1/2q2/[(1/4r)^2]
1/4 : 1/16 = 1/4 * 16 = 4 =>c) wzrośnie 4 razy
Wyjaśnienie:
Korzystamy ze wzoru Coulomba
[tex]F = k\cdot\frac{q_1\cdot \frac{1}{2}2}{r^{2}}\\\\F_1 = k\cdot\frac{\frac{1}{2}q_1\cdot\frac{1}{2}q_2}{(\frac{1}{4}r)^{2}} = k\cdot\frac{\frac{1}{4}q_1\cdot q_2}{\frac{1}{16} r^{2}} = \frac{\frac{1}{4}}{\frac{1}{16}}\cdot k\cdot\frac{q_1\cdot q_2}{r^{2}} = 4\cdot k\cdot\frac{q_1\cdot q_2}{r^{2}} =\boxed{4F}[/tex]
