Answer:

Angular Momentum of a particle of mass m moving with velocity V along a line y=x+5 about a perpendicular axis passing through origin O is zero.

Explanation:

The angular momentum of a particle of mass m, moving with velocity V along a line y = x + 5, about a perpendicular axis passing through origin O can be calculated by using the following formula:

  • L = r x mv

  • Where,
  • r is the position vector of the particle with respect to the origin O.
  • m is the mass of the particle.
  • v is the velocity of the particle.

  • In this case, we need to find the position vector of the particle with respect to the origin. The equation for the line y = x + 5 can be re-written in vector form as r = xi + (x + 5)j, where i and j are the unit vectors in x and y direction respectively.

  • Substituting the values in the formula, we get

  • L = (xi + (x + 5)j) x mv = m(xi x vj - (x + 5)j x vi)

  • Since the particle is moving along the line y = x + 5, we have vi = i and vj = 1. Hence,

  • L = m(-i x vj) = - mvi

  • The magnitude of the angular momentum is given by |L| = mv, and its direction is perpendicular to the plane of the particle's motion.
