The top of the atmosphere is at about 400kV with the respect to the surface of the earth, corresponding to an electric field that decreases with attitude. Near the surface of the earth the field is about `100Vm^(-1)` Still, we did not get an electric shocks as we step out of our house into the open because (assume the house to be a steel cage so that there is no field inside)

Options

A. Our body and the ground forms an equipotential surface
B. The atmosphere is not a conductor
C. There is a pd between out body and the ground
D. `100vm^(-1)` is not a high electric filed so that we do not feel the shock

Answer

A
