The earth’s potential is taken as

Right Answer is:

Zero

SOLUTION

Why the electric potential of Earth is zero?

For the measurement of level, we have a standard or a zero level, that is sea level and for the measurement of temperature, a zero of temperature, that is the temperature of melting ice, so also for the measurement of potential, we must have a standard or a zero of potential. The potential of the earth is taken to be zero of potential. For this purpose, the earth has been chosen because of its huge size, so that the small charges with which we have to deal with, if given to it or taken from it, produce no change in its potential.

Thus, a body whose potential is higher than that of the earth is said to have positive potential and one whose potential is lower than that of the earth is said to have a negative potential.
