    The position vector of a particle in a circular motion about the origin sweeps out equal area in equal time. Its
    (a) velocity remains constant
    (b) speed remains constant
    (c) acceleration remains constant
    (d) tangential acceleration remains constant.
    digAnsr:   b,d
    Ans : (b) speed remains constant
    (d) tangential acceleration remains constant
    If the speed is constant, the position vector of the particle sweeps out equal area in equal time in circular motion.
    Also, for constant speed, tangential acceleration is zero, i.e., constant.
