A) constant in magnitude as well as direction
B) constant in direction
C) constant in magnitude
D) constant
Correct Answer: A
Solution :
The circular disc of radius R rolls without slipping. Its centre of mass is C and P is point where body is in contact with the surface at any instant. At this instant, each particle of body is moving at right angles to the line which joins the particle with point P with velocity proportional to distance. In other words the combined translational and rotational motion is equal to pure rotation and body moves constant in magnitude as well as direction.You need to login to perform this action.
