Maritza Koch · Answer 1

The initial neutral rod would be induced with negative charges.

Explanation:

This process is called charging by induction. When you bring the charged rod close to that of the neutral, the charges in it would be redistributed. The positively charged rod attracts the negative charges within the neutral rod and repel like charges. Touching the neutral with hand causes the positive charge to be neutralised due to earthing. Thus the neutral rod has now been charged negatively.

Answer:The rod touching your hand will have a Negative charge.

Explanation: This phenomenon is described as charging by induction, the other iron rod became charged as a result the repulsion force existing between the positively charged iron rod and the electronic forces around the election sphere. This make it different from the charging done by contact where both iron rods have close contact and electron transfer is achieved through contact. The shows that an electric charge can be persuaded and caused to transfer to another metallic particle without physical contact with the charged metallic particle.
