Question

Два одинаковых проводящих шара исходно заряжены в первом имеется 33 тысячи электронов с несконпенсированным зарядом во втором 17 тысяч протонов с несконпенсированным зарядом. Затем шары привели в соприкосновение и снова разнесли на первоначальное расстояние. Как взаимодействуют заряженные шары до (А) и после (В) соприкосновения?

Answer 1

До соприкосновения они притягивались т.к. были разноименно заряжены. После соприкосновения будут отталкиваться т.к. заряды шаров будут оба одного знака.

Answer 2

Interaction between charged spheres before and after contact

Before the spheres come into contact, they each have a certain number of charged particles with unbalanced charges. The first sphere has 33,000 electrons with an unbalanced charge, while the second sphere has 17,000 protons with an unbalanced charge.

When the spheres are brought into contact, the excess charge on one sphere will redistribute itself to the other sphere until both spheres have the same potential. This process is known as charge transfer or charge equilibration.

After contact, the excess electrons from the first sphere will transfer to the second sphere, neutralizing the unbalanced charge on both spheres. As a result, both spheres will have the same charge, which will be a combination of the initial charges on the spheres.

It's important to note that the charge transfer occurs due to the repulsion between like charges (electrons repel electrons and protons repel protons) and the attraction between opposite charges (electrons attract protons). This redistribution of charges ensures that the total charge of the system remains conserved.

In summary, before contact, the spheres have unbalanced charges, and after contact, the excess charge is transferred between the spheres, resulting in both spheres having the same charge.
