A charged insulator and an uncharged metal object near each other

(a) Exert no electric force on each other.
(b) Repel each other electrically.
(c) Attract each other electrically.
(d) Attract or repel, depending on whether the charge is positive or negative.

Expert Solution

A charged insulator and an uncharged metal object attract each other electrically. Since, when a charged insulator is taken nearer to an uncharged metal, an opposite charge is developed on the surface of the metal object. Hence, these two attract each other electrically.

Therefore, the correct answer is (c).

The correct answer is (c).

What happens when a charged non-conductor is placed near an uncharged conductor body? Explain They repel each other. They attract each other. They may attract or repel each other, depending on whether the charge on the insulator is positive or negative. They exert no electrostatic force on each other. The charged insulator always spontaneously discharges
