Question

A particle with position vector $r$ has a linear momentum p. Which of the following statements is true is respect of its angular momentum $L$ about the origin?\

Professor PC Thomas Classes · Answer

(D) : Angular momentum L is given as\ $\mathrm{L}=\overrightarrow{\mathrm{r}} 	imes \overrightarrow{\mathrm{p}}=\mathrm{rp} \sin 	heta$\ $\overrightarrow{\mathrm{r}}=$ position vector of the particle w.r.t origin.\ $\overrightarrow{\mathrm{p}}=$ its linear momentum.\ $\overrightarrow{\mathrm{r}} 	imes \overrightarrow{\mathrm{p}}$ is maximum when p is perpendicular to ri.e. $	heta=90^{\circ}$.\
