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. 2) As a proton moves in a direction perpendicular to the electric field lines A) it is moving from 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.

Solution

1

D) because a positive charge moves from high potential to low potential(Electric field always points towards High potential to low potential) and a positive charge has higher potential energy at higher potential

2)

E) because while moving perpendicular to electric field lines the proton moves along equipotential plane and its potential does not change which implies its potential energy does not change.
