Question

State whether given statement is True or False.
Electric field of the earth can practically be used as a means of flight?

• A. True
• B. False

Answer 1

The correct option is B False

Through theoretically it appears as flying may be achieved with electric field of earth but the electric field is so small that a very big charge is required on the other body. The streamlining condition would demand making edges or sharp corners from where charge will leak by means of carona discharge. Practically we can not use the electric field of the earth to flight.
