Question

Два тіла А і В мають електричні заряди qa =0 Кл і qв= - 30 Кл відповідно. Чому станут рівні їх заряди, після дотику?​

Answer 1

Ответ:

Объяснение:

Після дотику іх заради будут дорівнювати -30

q1+q2=0-30=-30

Answer 2

Electric Charge Interaction

When two bodies with electric charges come into contact, the charges on the bodies may redistribute. If bodies A and B, with charges qA and qB respectively, come into contact, their charges may redistribute due to the principle of conservation of charge. According to this principle, the total charge before and after the interaction remains constant.

Redistribution of Charges

When the two bodies come into contact, the charges redistribute in such a way that the final charges on the bodies are equal. This redistribution occurs because the net charge of the system must remain conserved. If one body has a charge of 0 C and the other has a charge of -30 C, after coming into contact, the charges will redistribute to make the final charges on both bodies equal.

Conservation of Charge

The redistribution of charges occurs in a way that the total charge of the system remains the same. This means that the final charges on the bodies will be such that they add up to the initial total charge of the system. In this case, the redistribution will result in both bodies having charges of -15 C each, making the total charge of the system 0 C, which was the initial total charge.

Therefore, after coming into contact, the charges on bodies A and B will become equal and have a value of -15 C each. This redistribution ensures that the total charge of the system remains conserved.
