A solid cylinder is given a velocity vq and an angular speed uq in the anticlockwise direction and then it is placed gently on a very long rough plank (initially at rest) as shown in the figure. Then, choose the incorrect statement:
Text Solution
Verified by ExpertsThe correct answer is:
D
the angular momentum of the disc about any point on the horizontal surface remains conserved
Initial velocity of point of contact of disc is in forward direction.
Hence friction is in backward direction and kinetic in nature.
Net force on the system is zero. So momentum is conserved.
