One end of the 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 a circle with speed \(v\), the net force on the particle (directed towards the centre) will be: (\(T\) represents the tension in the string)

1. \(T \) 2. \(T+\frac{m v^2}{l} \)
3. \(T-\frac{m v^2}{l} \) 4. \(\text{zero}\)
