Question
A negatively-charged rod is brought close to (but does not touch) two neutral spheres that are in contact with each other but insulated from the ground. If the two spheres are then separated, what kind of charge will be on the spheres?
A negatively-charged rod is brought close to (but does not touch) two neutral spheres that are in contact with each other but insulated from the ground. If the two spheres are then separated, what kind of charge will be on the spheres?
The spheres do not get any charge. Both spheres become positive. The sphere near the charged rod becomes negative and the other one becomes positive. <-------- NOT THE ANSWER Both spheres become negative. The sphere near the charged rod becomes positive and the other one becomes negative.Explanation / Answer
by induction process,the near sphere gets positive charge where as other one gets negatively charged
when we brought the negatively charged rod near by one sphere ,then all the positive charges will induce near by side to the rod
all other negative charges will settle nearer to the other sphere,on which already negative charges will induces on the near side to the first sphere.So these negative from first sphere and positive from second sphere will get canceld
So the charges remaining are positive charges on near sphere and negative charges on the other one
