Answer:
Explanation:
Force between two charges is given by the following expression
F = [tex]\frac{KQ_1Q_2}{d^2}[/tex] Q₁ and Q₂ are two charges and d is distance between two.
.1 = [tex]\frac{KQ_1Q_2}{d^2}[/tex]
If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.
Force F = .3 N
If charge becomes one fourth , force also becomes one fourth .
F= [tex]\frac{.1}{4}[/tex]
= .025 N.
