• # question_answer During a thunderstorm, Ram and his friends were in the middle of a jungle. His friends were standing under a tree. Rohan advised them not to stand there. Rather he suggest they should move back to the bus. He explained them that they are safe inside the bus due to electrostatic shielding. (i) What are the values exhibited by Ram. (ii) What is electrostatic shielding?

Answer:

${{n}_{e}}=5\times {{10}^{22}}{{m}^{-3}},$ ${{n}_{h}}=4.5\times {{10}^{9}}{{m}^{-\,3}}$

 (i) Concern for others, understanding the concept and ability to apply it in our daily life. (ii) If we make a region free from electric field, this phenomenon is called electrostatic shielding. It is based on the fact that the electric field inside a conductor is always zero.
