GEOLOGY

Detailed explanation-1: -A charged object (A) comes into contact with an uncharged object (B). In the process, object A loses electrons and object B gains electrons. Which of the following is true? Object B now has a negative charge.

Detailed explanation-2: -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.

Detailed explanation-3: -Consider an uncharged metal rod A kept on an insulating stand and a negatively charged conductor B as shown in below figure (1). The process of charging the uncharged object by bringing it in contact with another charged object is called charging by conduction.

Detailed explanation-4: -Answer and Explanation: An object becomes negatively charged when it gains electrons.

Detailed explanation-5: -When it loses electrons it becomes positively charged. When an object gains electrons it becomes negatively charged.
