JEE Main & Advanced Physics Two Dimensional Motion Question Bank Uniform Circular Motion

  • question_answer
    A car moves on a circular road.  It describes equal angles about the centre in equal intervals of time. Which of the following statement about the velocity of the car is true                                     [BHU 2001]

    A)             Magnitude of velocity is not constant  

    B)             Both magnitude and direction of velocity change

    C)             Velocity is directed towards the centre of the circle

    D)             Magnitude of velocity is constant but direction changes

    Correct Answer: D

    Solution :

                    As body covers equal angle in equal time intervals. its angular velocity and hence magnitude of linear velocity is constant.
