A charged bead is sliding freely through a string held vertically under tension. An electric field is applied parallel to the string so that the bead stays at rest at the middle of the string. If the electric field is switched off momentarily and switched on again, then
- A the bead falls off momentarily and then stopped
- B the bead moves downwards and then moves upwards
- C the bead moves downwards with constant
- D the bead moves downwards with constant velocity
