In the motion of charged particles through a region containing either only uniform electric field 
or only uniform magnetic field or both, certain properties are listed in column I and their possible reason or explanations are given in column II. (Here V denote the velocity of the particle and force means the force acting on the particle)
Column-I | Column-II |
(i) V cannot remain constant in only | [A] = |
(ii) Magnitude of will remain constant if only B is present | [B] The force acting on the particle will always be normal to its velocity |
(iii) may remain constant if only is present | [C] is parallel to |
(iv) may remain constant if both and are present | [D] There must be some component of the force acting on the particle in direction of its motion at same time. |
