Answer #1

The tangential linear acceleration is given by the product of angular acceleration of the disc and the radial distance from.the axis of rotation.

As for a rotating disc, the angular acceleration will be constant for the complete disc. As the angular acceleration is constant, the tangential acceleration will be dependant on radial distance from the axis of rotation and will be directly proportional to it.

Hence, the tangential acceleration for a point on the edge rim will be greater than the tangential acceleration for any point inside the disc.

Hence the statement is TRUE
