Question

A vector of magnitude 10 units perpendicular to a vector is equal to a + c minus ke and coplanar with the vectors b vector is equal to 2 y - 3 - k and c vector is equal to a + 20 - ke age

Answer 1

Answer:

If the linear momentum of any particle is p=mv and its position vector from any constant point be r then abgular momentum of the particle is given by

L = r×p = m(r×v) (1)

Angular momentum is a vector quantity and its direction is perpandicular to the direction of r and p and could be found out by right hand screw rule.

From equation 1 scalar value or magnitude of angular momentum is given as

|L|=rpsinθ (2)

where V is the angle between r and p.

For a particle moving in a circular path

v=ω×r; (3)

where ω is the angular velocity.
