Question

Можно ли с помощью отрицательно заряженной палочки зарядить тело положительным зарядом? Как это сделать? Какие тела возможно зарядить таким образом?

Answer 1

Можно
С помощью электростатической индукции
Приблизить палочку к незаряженному теле а потом прикоснуться пальцем с проивоположной от палочки стороны

Answer 2

Can a negatively charged rod charge a body positively? How can this be done? Which bodies can be charged in this way?

Yes, a negatively charged rod can charge a body positively through a process called "charging by induction." When a negatively charged rod is brought near a neutral conducting body, it repels the electrons in the body, leaving the side of the body closest to the rod with a net positive charge. This is because the electrons are repelled by the negative charge of the rod, leaving the positive charges behind. The process involves the redistribution of charges rather than the transfer of charges from the rod to the body.

This method can be used to charge various types of bodies, including conductors and insulators. Conductors allow the charges to move freely, so the redistribution of charges is easier. Insulators, on the other hand, do not allow charges to move as easily, but they can still be charged by induction.

In summary, a negatively charged rod can charge a body positively through the process of charging by induction, and this method can be applied to both conductors and insulators.
