Class 11 Physics Rotational Motion Vector Product

Vector Product

  • Vector product (cross product) of two vectors a and b is a × b = ab sinΘ  = c ,     where Θ is angle between a & b
  • Vector product c is perpendicular to the plane containing a and b.
  • If you keep your palm in direction of vector a and curl your fingers to the direction a to b, your thumb will give you the direction of vector product c

Properties of vector product



Example - Calculate the cross product between a= (3, −3, 1) and b = (4, 9, 2)
