Two equal spheres, labeled A and B in the figure, are attached to a massless rod with a frictionless pivot at the point P.The system is made to rotate clockwise with angular speed $ \omega $ on a horizontal, frictionless tabletop.Sphere A collides with and sticks to another equal sphere that is at rest on the tabletop.Note: the masses of all three spheres are equal. What is the angular speed of the system immediately after the collision?
A)($ \omega $)
B)0.82$ \omega $
C)0.60$ \omega $
D)0.56$ \omega $
E)0.29$ \omega $
