physics

To understand the electric force between charged and uncharged conductors and insulators. What is the nature of the force between balls A and B? When a test charge is brought near a charged object, we know from Coulomb's law that it will experience a net force (either attractive or repulsive, depending on the nature of the object's charge). A test charge may also experience an electric force when brought near a neutral object. Any attraction of a neutral insulator or neutral conductor to a test charge must occur through induced polarization. In an insulator, the electrons are bound to their molecules. Though they cannot move freely throughout the insulator, they can shift slightly, creating a rather Assume throughout this problem that the balls are brought very close together. What is the nature of the force between bails A and B?

Explanation / Answer

suppose test charge is negative,if it gets attracted towards A... then object A must be positively charged.......and same test charge get repelled by B,so Bmust be negatively charged... so A and B are of opposite nature......

So there will be attraction force ,strongly attracted..... as coulomb force is strong force
