  • Question 1/10
    4 / -1
    A round uniform body of radius R, mass M and moment of inertia I, rolls down (without slipping) an inclined plane making an angle θ with the horizontal. Then its acceleration is
    Solutions

  • Question 2/10
    4 / -1
    Two identical discs of same radius R are rotating about their axes in opposite directions with the same constant angular speed ω. The discs are in the same horizontal plane. At time t = 0, the points P and Q are facing each other as shown in the figure.The relative speed between the two points P and Q is vr . In one time period (T) of rotation of the discs, vr as a function of time is best represented by
