Question

The figure to the right shows three points in an electric field. The potentials of the points obey the relationship VA > VB > VC. The potential decreases uniformly from points A to. C. A positively charged particle is constrained to move along the line drawn. If the particle is released from rest at point B, which of the following best describes its motion? Select One of the Following: (a) The particle stays at rest at point B, (b) The particle moves toward point A with constant speed. (c) The particle moves toward point A with decreasing speed. (d) The particle moves toward point A with increasing speed. (e) The particle moves toward point C at a constant speed. (f) The particle moves toward point C with decreasing speed. (g) The particle moves toward point C with increasing speed.

Explanation / Answer

since VA> Vb>Vc

as partice is realesed at Vb, it alwasy tends to place it self in low potential

thus it moves towards the region of Vc, at increasing spped

option g is correct
