The position vector of a particle of mass m moving with a constant velocity \overrightarrow{v} is given by \overrightarrow{r}=x(t) \stackrel{\^}{i}+b \stackrel{\^}{j}, where b is a constant. At an instant, \overrightarrow{r} makes an angle \theta with the x-axis as shown in the figure. The variation of the angular momentum of the particle about the origin with \theta will be
