1.	The surface charge density of Earth is σ = -1.33 nC/m2. That is about 8.3 × 109 electrons per square metre. If that is the case why don’t we feel it?
Answer» The Earth along with its atmosphere acts as a neutral system. The atmosphere (ionosphere in particular) has nearly equal and opposite charge. As a result, there exists a mechanism to replenish electric charges in the form of continual thunderstorms and lightning that occurs in different parts of the globe. This makes average charge on surface of the Earth as zero at any given time instant. Hence, we do not feel it.
