Q44 / 223 · NTA Abhyas (NEET) 2020 · Physics · Rotational Motion
A circular disc of radius rolls without slipping along the horizontal surface with constant velocity . We consider a point on the surface of the disc. Then, the acceleration of point is
- Correct answerAConstant in magnitude
- BConstant in direction
- CConstant in magnitude as well as direction
- DNone of the above
Solution
With respect to centre , all points on circumference is moving in a circle with angular velocity . Its acceleration towards centre in and different point has direction.
Hence, the correct answer is option: 'A'.
