Question

Which of the following is NOT the property of equipotential surface?

Options

  • They do not cross each other.

  • The rate of change of potential with distance on them is zero.

  • For a uniform electric field, they are concentric spheres.

  • They can be imaginary spheres.

  • The work done in carrying a charge from one point to another on an equipotential surface is zero.

Solution

For a uniform electric field, they are concentric spheres.

Explanation:

As all other statements are correct. In a uniform electric field, equipotential surfaces are never concentric spheres but are planes ⊥ to Electric field lines.

The discharging current in the atmosphere due to the small conductivity of air is known to be 1800 A on an average over the globe. Why then does the atmosphere not discharge itself completely in due course and become electrically neutral? In other words, what keeps the atmosphere charged?


What are the forms of energy into which the electrical energy of the atmosphere is dissipated during a lightning?
(Hint: The earth has an electric field of about 100 Vm−1 at its surface in the downward direction, corresponding to a surface charge density = −10−9 C m−2. Due to the slight conductivity of the atmosphere up to about 50 km (beyond which it is good conductor), about + 1800 C is pumped every second into the earth as a whole. The earth, however, does not get discharged since thunderstorms and lightning occurring continually all over the globe pump an equal amount of negative charge on the earth.)
