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

Options

  1. AL acts along P
  2. BL is maximum when P is perpendicular to r
  3. CL acts along r
  4. DL is maximum when P and r are parallel

Correct answer

B. L is maximum when P is perpendicular to r

Step-by-step solution

The angular momentum of the particle is given by L = r p Its magnitude is L = rp L will be maximum when =90^
