Question

(8%) Problem 2: Since a proton has a positive charge, it will move in an electromagnetic field under the Coulomb force. When a proton moves in the same direction as the electric field is pointing, we can conclude that: OIt moves from a low potential to a high potential and its electric energy decreases OIt moves from a low potential to a high potential, and its electric energy increases. It moves from a high potential to a low potential and its electric energy decreases. Gra Ded Poten OBoth its electric potential and electrie potential energy stay constant. Subn It moves from a high potential to a low potential and its electric energy increases detail Feedback Hints: 4-L deduction per hin. Hints remaining: Feedback:-deduction per feedback

Explanation / Answer

problem 2 :

It moves from hight potential to low potential and its electric energy decreases

electric field moves from high to low potential . hence if proton is moving in the direction of electric field , it moves from high to low potential. as the proton moves in the direction of electric field , it gains kinetic energy due to electric force experience by the electric field in the same direction. This increase in energy comes from decrease in the electric energy.
