The seconds hand of a watch has length math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn6/mnmo /momicm/mi/math. Speed of end point and magnitude of difference of velocities at two perpendicular positions will be
(a) \( 6.28 \) and \( 0 \mathrm{~mm} / \mathrm{s} \)
(b) \( 8.88 \) and \( 4.44 \mathrm{~mm} / \mathrm{s} \)
(c) \( 8.88 \) and \( 6.28 \mathrm{~mm} / \mathrm{s} \)
(d) \( 6.28 \) and \( 8.88 \mathrm{~mm} / \mathrm{s} \)
