I know I am asking out of my limits, but i felt relaxed thinking about this.
Now I read somewhere about quantum fluctuations (that energy can be generated in randomly at two positions where total sum of the energy is zero.
So i researched about it a little and found that they are completely probabilistic (Heisenberg' principle)
- Are they observable?
- And in electrostatics in problems where cavity is involved we fill the cavity with positive and negative charge (so i thought of if i fill the cavity with the charge(positive or negative) of the rest of the body) and take away the rest of its counterpart charge very far away from the body)---------------but that would be a very probabilistic case(might be 1 in trillions). So this made me think of the question 1
I know it might be difficult for all to explain this to a high school student but I have faith that you will find a way :)
