All points in a rigid body move with the same velocity and acceleration if the rigid body is subjected to General plane motion None of the above Rotation about a fixed axis Translation

Solution

All points in rigid body move with same velocity and accelration if rigid body is subjected to linear or purely translational motion as during translation motion the accelration and velocity of whole body would be same as of centre of mass of the body. While in rotational motion many particles would be rotating in different paths with different radii so, even if there is same angular velocity ( pure rotational motion) but velocity of all particles cannot not be same.
