Question

3) As an electron moves in the direction of the electric field lines A) it is moving fron low potential to high potential and gaining electric potential energy. B) it is moving from low potential to high potential and losing electric potential energy C) it is moving from high potential to low potential and gaining electric potential energy D) it is moving from high potential to low potential and losing electric potential energy E) both its electric potential and electric potential energy remain constant

Explanation / Answer

Magnetic field lines are always directed from low potential to higher potential.

In general electron always moves to the opposite direction of electric field in order to convert its stored potential energy into kinetic energy but If the electron moving in the direction of electric field then it must be moving from low potential to higher potential and gaining the potential energy.

Option (a) is correct
