Question

we can say that a charged object attracts an uncharged object by first charging it through induction?....explain it

Answer 1

Due to induction, charges opposite to that of the charged body accumulates in some parts of the uncharged object( parts nearer to the charged object ).
We know that unlike charges attract each other.
So the objects attract.

Answer 2
