The magnitude of the average electric field normally present in the atmosphere just above the surface of the Earth is about 150 N/C, directed inward towards the center of the Earth. This gives the total net surface charge carried by the Earth to be: [Given \[{{\varepsilon }_{0}}=8.85\times {{10}^{-12}}{{C}^{2}}/N-{{m}^{2}},\]\[{{R}_{E}}=\]\[6.37\times {{10}^{6}}m\]] magnitude of the average electric field normally present in the atmosphere just above the surface of the Earth is about 150 N/C, directed inward

1.	The magnitude of the average electric field normally present in the atmosphere just above the surface of the Earth is about 150 N/C, directed inward towards the center of the Earth. This gives the total net surface charge carried by the Earth to be: [Given \[{{\varepsilon }_{0}}=8.85\times {{10}^{-12}}{{C}^{2}}/N-{{m}^{2}},\]\[{{R}_{E}}=\]\[6.37\times {{10}^{6}}m\]] magnitude of the average electric field normally present in the atmosphere just above the surface of the Earth is about 150 N/C, directed inward
