- #34Two particles A and B are moving in uniform
circular motion in concentric circles of radii
``r_A`` and ``r_B`` with speed ``v_A`` and ``v_B``
respectively. Their time period of rotation is
the same. The ratio of
angular speed of A to that of B will be :
(1) ``r_A : r_B``
(2)``v_A : v_B``
(3)``r_B : r_A``
