  • Assertion When a car takes a circular turn on a horizontal road, then normal reaction on inner wheels is always less than the normal reaction on outer wheels. Reason This is for rotational equilibrium of car.

    A
    If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
    B
    If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
    C
    If Assertion is true but Reason is false.
    D
    If Assertion is false but Reason is true.

  • A car drives anticlockwise (conterclockwise) around a flat, circular curve at constant speed, so that the left, front wheel traces out a circular path of radius R = 10 m. If the width of the car is 2m, what is the ratio of the angular velocity about its axis of the left, front wheel to that of the right, front wheel, of the car as it moves through the curve? Assume the wheels roll without slipping.

    A
    `(4)/(3)`
    B
    `(1)/(3)`
    C
    `(6)/(5)`
    D
    `(5)/(6)`
