Respuesta :
When sphere A and B are brought in contact and separated, charge on each sphere becomes [2x10^-6 + (-4x10^-6)]/ 2 = -1x10^-6 C.
That is, charge is equally separated and is the average of charges on both spheres. The reason behind equal charge on both spheres after separation is, when they are kept in contact, their potential difference becomes same.

Sphere A will have a charge of -1 x 10⁻⁶ C. Option C is correct.
What is the charge?
When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.
Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term "neutral" refers to an item that has no net charge.
When spheres A and B come into contact and then split. Charge on each sphere is found as;
[tex]\rm Q_A= \frac{2 \times 10^{-6}+(-4\times 10^{-6})}{2} \\\\ Q_A=-1 \times 10^{-6} \ C[/tex]
Sphere A will have a charge of -1 x 10⁻⁶ C.
Hence,option C is correct.
