In the figure given below, the position-time graph of a particle of mass \( 0.1 \mathrm{~kg} \) is shown. The impulse at \( t=2 \mathrm{sec} \) is [AIIMS 2005]
(a) \( 0.2 \mathrm{~kg} m \mathrm{sec}^{-1} \)
(b) \( -0.2 \mathrm{~kg} m \mathrm{sec}^{-1} \)
(c) \( 0.1 \mathrm{~kg} \mathrm{mec}^{-1} \)
(d) \( -0.4 \mathrm{~kg} \mathrm{~m} \mathrm{sec}{ }^{-1} \)
