If the earth has net charge that is not zero. Is it possible to adopt the earth as a standard reference point of potential and assign the potential V = 0 to it?

Standard electrode potential is assigned a …..Potential at all temperatures

Why do we often regard the potential of the earth to be zero?

Can a body have charge and still be at zero potential?

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0Xx10^24 kg , radius = 6400 km.

Assume that earth has a charge of surface density 1 electron per metre^2 . Calculate the earth's electric potential just outside the earth's surface.

An object of mass m is raised from the surface of the earth to a heigt equal to the radius of the earth , that is, taken from a distance R to 2R from the centre of the earth. What is the gain in its potential energy?
