When a person holds a negatively charges metal rod... | WAEC SSCE - Physics - 2013 (Objective)

Question 1 Report

When a person holds a negatively charges metal rod and stands bare-footed on the ground, how will the charges leak?

negative charges flows to the ground through the person's body

positive charges flow from the ground through his body to neutralize the negative charges

positive charges in the air neutralizes the negative charges the person is holding

negative charges will leak through the air

Answer Details

When a person holds a negatively charged metal rod and stands bare-footed on the ground, the negative charges will flow to the ground through the person's body. This is because the human body is a good conductor of electricity, allowing charges to flow easily through it. When a person is standing on the ground, they are in contact with a large conductive surface (the earth), which provides a pathway for the charges to flow away from the person's body and into the ground. This process is called grounding or earthing, and it helps to prevent the buildup of static electricity on the person's body.
