Question :
Why can we easily move our hands in the air but do the same through a plank of wood, we need a karate expert? Explain.Submitted on 2/1/2024 | Answered by Vandana Rana
Answer :
There will be a weak force of attraction between the particles in the air. So we can move our hands-on air whereas the particles in solid plank are closely packed and a strong force of attraction exists between them.Hence it needs a huge force to overcome the attraction which a karate expert can do.
