Q44 / 223 · NTA Abhyas (NEET) 2020 · Physics · Rotational Motion

A circular disc of radius R rolls without slipping along the horizontal surface with constant velocity v0. We consider a point A on the surface of the disc. Then, the acceleration of point A is

  • Correct answer
    A
    Constant in magnitude
  • B
    Constant in direction
  • C
    Constant in magnitude as well as direction
  • D
    None of the above

Solution

With respect to centre ω, all points on circumference is moving in a circle with angular velocity ω . Its acceleration towards centre in ω 2 R and different point has direction.

Hence, the correct answer is option: 'A'.
