Question

Explain how an uncharged object may become positively charged.​

Answer 1

Uncharged objects become positively charged by other objects with a positive charge when they come into contact.

Answer 2

When a charged object is brought near an uncharged object, the uncharged object becomes charged with the opposite charge.

Step-by-step explanation:

Charging by induction explains how an uncharged object gets charged when a charged object is brought near it. When a charged object is brought near an uncharged object, the uncharged object becomes charged with the opposite charge. Since unlike charges attract each other, these two objects attract each other.
