MHT CET Physics question
Statement 1: A disc rolls without slipping on a horizontal surface and the linear speed of its centre of mass is . The rotational speed of the particles on its rim at the top of the disc will be Statement 2: The disc rolls as if it is rotating about the point of contact with the horizontal surface
Answer: (A)
Solution
In pure rolling the disc turns instantaneously about the contact point, so the top point (twice as far from the contact point as the centre) moves at (statement
