A body moving with constant speed in a circular path has **[OJEE 2004]**

(A)constant angular momentum (about the centre)Correct
(B)constant (vector) acceleration
(C)constant velocity
(D)no (net) work done on itCorrect

Answer: (A),(D)

Solution

Since speed is constant and the radius is fixed, angular momentum about the centre is constant both in magnitude and direction (B and C are false because the acceleration and velocity
