Question

. A particle of mass 0.2kg is moving with
linear velocity (i-j+2k). If the radius vector
r = 4i+j-k, the angular momentum of the
particle is

Actually Welcome to the Concept of the Kinematics

Since we know that,

L = m *( v × R )

here, we have to get the cross product of the velocity vector and the Radius Vector,

so after solving we get as

Answer 2

Answer:

the answer for the given questions√4.28 units
