Question

An electron is placed in a uniform vertical electric field. In order to float (at rest) the electron above the ground what must be the direction of the electric field?

An electron is placed in a uniform vertical electric field. In order to float (at rest) the electron above the ground what must be the direction of the electric field? O upward downward None of the above as no force thus no field is needed to keep it at rest.

Answer 1

Answer: Downward

Explanation:

The overcome the é must neglegible gravitation pull to float in electric field, so the electric field must exert a force upwards to keep the é floating fore due to electric field faret, Electric field must be downwards because Elechic field is directed towards ove charge this tre to + f =-ef → م mg Result = floating ofe
