One end of string of length l is connected to a particle of mass 'm' and the other end is connected to a small peg on a smooth horizontal table. If the particle moves in circle with speed 'v' the net force on the particle (directed towards centre) will be (T represents the tension in the string) :-

T - mv² 1 -
T - mv² 1 - Zero
- T

Correct Option: D
Net force on particle in uniform circular motion is centripetal force
 |  | ||
| l |
which is provided by tension in string so the net force will be equal to tension i.e., T.
