The answer is E. Please explain. Thank you

Base your answer to the following question on the following information. Five partiles,all of the same mass and initial horizontal velocity, are sent through an electric field directed upwards and follow the paths depicted by A, B, C, D, and E, respectively. Et Which of the following statements below is true? A) All of the particles moved to a higher level of electric potential. B) Particles A, B, C, D and E are at equipotentials. C) Particle E moved to a lower electric potential D) Particle A is at a higher electric potential than Particle B E) Particle C and Particle D are at equipotentials.

Explanation / Answer

Since electric Field is pointed upwards. Electric Potential decreases in upward direction. Further, from the definition of Equipotential surface, It should be perpendicular to the electric Field,

Therefore, Points C & D lying on such a surface, which is perpendicular to the electric Field, hence both are at same potential

Answer (E)
