1.	A particle with position vector has a linear momentum p. Which of the following statements is true in respect of its angular momentum L about the origin?
Answer» L acts along p L acts along R L is maximum when p and r are parallel. L is maximum when p is perpendicular to r. Solution :Angular MOMENTUM `VECL` is given as `vecL = vecr xx vecp = rp sin theta` where `, vecr`= POSITION vector of the particle w.r.t. origin `vecp`= its linear momentum . `vecr xx vecp` is maximum when `vecp` is perpendicular to `vecr ` i.e., `theta = 90`
