when a charged object is brought near an uncharged object , the uncharged object aquire opposite charges of equal strength through electrostatic induction. This cause a pair of unlike charges on the either bodies .
so , the uncharged object must somehow gain a unlike charge is correct

Question 3
what happens when a charged Insulator is placed near an uncharged metallic object? They repel each other. They attract each other. They exert no electrostatic force on each other. The charged Insulator always spontaneously discharges. They may attract or repel each other, depending on whether the charge on the insulator is positive or negative. 3. -11 points Three charges are arranged as shown in the figure below. Find the magnitude and direction of the electrostatic force on the...
