PhysicsEasysingle choice
A disc is rotated about its axis with a certain angular velocity and lowered gently on a rough inclined plane as shown in the figure then
Options:
Answer:
A
Solution:
Here kinetic friction force will balance the force of gravity. So it will rotate at its initial position and will not move up or down. As its angular velocity becomes zero (friction also becomes zero), it will move downwards.
