Автор ответа: kmike21

Сила Кулона F=kq₁q₂/r²
у нас заряды были q₁ и q₂, а стали 2q₁ и 2q₂.
тогда сила Кулона станет k*2q₁*2q₂/r²=4kq₁q₂/r², то есть увеличится в 4 раза

One day thе oldest mouse says, "Come to my hole, mice. Iet us think what we can do about the cat." All the micе come to the hole of the oldest mouse. They begin to speak. They say that the cat is very bad. Many mice speak but nobody knows what to do about the cat. Then the youngest mouse says, "We do not hear when the cat comes to us. Let usput a bell on the cat's neck. The bell will ring, We shall run away." All the mice are very glad. "Our young friend has a good plan," they say. "Let us run and get a bell." But the oldest mouse says, "We can get a bell. Let us think who can put it on the cat's neck." 1 can't do that," says the youngest mouse. "We can't do that," say all the mice. "Well," says the oldest mouse, "I think the plan is not good if we can't fulfil it. I have another plan. Let us give the cat a nice bell as a birthday present."The cat's birthday is some days later.
