Vedclass · Answer

(B) The potential energy $U$ of a charge $q$ in an electric potential $V$ is given by $U = qV$.Since the Earth is considered to have a negative charge,the potential $V$ at the surface is negative. As we move the negative charge $q$ away from the Earth to a greater height,the potential $V$ becomes less negative (i.e.,it increases towards zero).Since $q$ is negative and $V$ is increasing (becoming less negative),the product $qV$ becomes more negative,but in terms of magnitude relative to the reference point,the potential energy increases as work is done against the electrostatic force of attraction between the Earth and the negative charge.

When a negative charge is taken at a height from the Earth's surface,its potential energy:
