JEE AdvancedPhysicsRotational MotionMultiple correct+4 / −2
A wheel of radius R and mass M is placed at the bottom of a fixed step of height R as shown in the figure. A constant force is continuously applied on the surface of the wheel so that it just climbs the step without slipping. Consider the torque τ\tauτ about an axis normal to the plane of the paper passing through the point Q. Which of the following options is/are correct? JEE Advanced 2017 Paper 2 Offline Physics - Rotational Motion Question 33 English
  1. A
    If the force is applied normal to the circumference at point P, then τ\tauτ is zero
  2. B
    If the force is applied tangentially at point S, then τe\tau eτe 0 but the wheel never climbs the step
  3. C
    If the force is applied at point P tangentially, then τ\tauτ decreases continuously as the wheel climbs
  4. D
    If the force is applied normal to the circumference at point X, then τ\tauτ is constant
