 When a mass is rotating in a plane about a fixed point, its angular momentum is directed along
  • a)
    A line perpendicular to the plane of rotation
  • b)
    The line making an angle of 45° to the plane of rotation
  • c)
    The radius
  • d)
    The tangent to the orbit
Correct answer is option 'A'. Can you explain this answer?

As we know that
Angular momentum L = m (r x v)
So, here angular momentum is directed along a line perpendicular to the plane of rotation.
