Physics - Electrostatics Question with Solution | TestHub

The magnitude of the average electric field normally present in the atmosphere just above the surface of the Earth is about $150 \mathrm{N}/\mathrm{C}$, directed inward towards the center of the Earth. This gives the total net surface charge carried by the Earth to be : [Given :${\in }_{\text{O}}=\text{8.85}\times 10^{-12}{\text{ C}}^2/{\text{N-m}}^2\text{, }{\text{R}}_{\text{E}}=\text{6.37}\times 10^6\text{m}$]
