How do you explain your choice?

when the rod is put near to sphere A a positive charge accumulated on it and a negative charge on sphere B but I am really confused i think that both spheres can be positive so if you have an answer pls help and explain it

 

[voko]

Your answer and your explanation are correct. Due to electrostatic induction, A becomes positive and B negative, and when they are separated, the charges are preserved.

Yes, you are correct. Static electricity refers to the buildup of electric charge on the surface of an object. This charge can be either positive or negative, depending on the movement of electrons. When an object gains electrons, it becomes negatively charged, and when it loses electrons, it becomes positively charged. These charges can interact with each other, leading to phenomena such as attraction or repulsion between objects. Understanding the properties and behavior of positive and negative charges is important in many areas of science, including electricity and magnetism, as well as in practical applications such as electronics and power generation.
