Question

What happens when a charged insulator is held near an uncharged metal object? a) They attract b) They repel c) It depends on the sign of the charge on the insulator d) Nothing happens Would life be different if the electron was positively charged and the proton was negatively charged? Two point charges attract each other with an electric force equal to 18N if one charge is doubled (the other charge remains the same), and the distance between them is tripled, what is the new force between them? What is the strength of the electric force between two protons confined to an atomic nucleus, a distance of only 2 times 10^-15 m apart? Find the net force on 4q (the lower-right charge) You should leave in component form, with i and j, and m terms of k. q. and a

Explanation / Answer

Ans: They attract each other

When we hold a charged insulator near by a uncharged metal, charge induction takes place on the metal which will induce the opposite charge. As the charges opposite (positive and negative) they attract with each other.
