A charged particle goes undeflected in a region containing electric and magnetic field. It is possible that (i) `vec(E) || vec(B). vec(v) || vec(E)` (ii) `vec(E)` is not parallel to `vec(B)` (iii) `vec(v) || vec(B)` but `vec(E)` is not parallel to `vec(B)` (iv) `vec(E)||vec(B)` but `vec(v)` is not parallel to `vec(E)` |
| Answer» `vec(E) || vec(B), vec(v)|| vec(E) or vec(E)` is not parallel to `vec(B)` | |
