Rotational Motion question

2017 · Shift 2 · Q49

JEE AdvancedPhysicsRotational MotionMultiple correct+4 / −2
A rigid uniform bar AB of length L is slipping from its vertical position on a frictionless floor (as shown in the figure). At some instant of time, the angle made by the bar with the vertical is θ\thetaθ. Which of the following statements about its motion is/are correct? JEE Advanced 2017 Paper 2 Offline Physics - Rotational Motion Question 32 English
  1. A
    Instantaneous torque about the point in contact with the floor is proportional to sin θ\thetaθ
  2. B
    The trajectory of the point A is parabola
  3. C
    The mid-point of the bar will fall vertically downward
  4. D
    When the bar makes an angle θ\thetaθ with the vertical, the displacement of its mid-point from the initial position is proportional to (1 −-− cos θ\thetaθ)
