Question

What happens when a charged sphere is bought near an uncharged sphere of same size??

Let the charged sphere be X and uncharged one be Y.

Answer 1

Hey !!
when an uncharged sphere is brought near a charged sphere then the uncharged sphere will always attracted towards the charged sphere .
Why ?
It's because in uncharged sphere the +ve and
-ve species are uniformly distributed. But when you bring a charged sphere (say positively charged them it will attract the uniformly distributed electrons to one side and the +ve species will gather at other side of the sphere . And if you bring a negatively charged sphere then same phenomenon will be observed.
Thus in each case the uncharged sphere will be attracted toward the charged sphere.
This phenomenon is called induction.

hope it will help you :)
