Question

4. Соломинка притягнулася до зарядженого тіла. Чи можна стверджувати, що соломинка була попередньо заряджена? Чи зміниться ваша відповідь, якщо ви спостерігаєтевідштовхування?​

Answer 1

Так,соломинка була попереденьо зарядженою
Ні,моя відповідь не зміниться тому що вона могла бути такого ж заряду як і заряджене тіло

Answer 2

Straw Attracted to Charged Object

When a straw is attracted to a charged object, it may not necessarily mean that the straw was previously charged. The attraction could be due to the polarization of the atoms within the straw in response to the electric field of the charged object. This phenomenon is known as electrostatic induction.

Electrostatic Induction and Attraction

Electrostatic induction occurs when the electric field of a charged object polarizes the atoms in a nearby uncharged object, causing it to be attracted to the charged object. This can happen even if the uncharged object was not previously charged itself. The polarization of the atoms within the uncharged object results in an overall attraction to the charged object.

Observing Repulsion

If repulsion is observed instead of attraction, it could indicate that the straw was initially charged with the same type of charge as the charged object. In this case, the like charges repel each other, causing the straw to be pushed away from the charged object.

In summary, the attraction of a straw to a charged object does not necessarily mean that the straw was previously charged. It could be the result of electrostatic induction, where the electric field of the charged object polarizes the atoms within the straw, leading to an overall attraction. If repulsion is observed, it may indicate that the straw was initially charged with the same type of charge as the charged object.
