Worked Solution & Example Answer:The boy in the photo is touching a charged globe that is at high voltage - Junior Cycle Science - Question g - 2011
Step 1
What property of electric charge causes the boy’s hair to stand on end and apart?
Answer
The property of electric charge that causes the boy's hair to stand on end and apart is known as 'like charges repel.' When the boy touches the charged globe at high voltage, the electrons in his hair are repelled by the like charges on the charged globe, causing his hair to stand up as they try to move away from each other.
Alternatively, this phenomenon can also be described in terms of 'static electricity,' where the accumulation of electric charge can lead to similar repulsive effects.
