Two identical cylindrical jobs are turned using (a) a round nosed tool of nose radius 2 mm and (b) a sharp corner tool having principal cutting edge angle = 450 and auxiliary cutting edge angle = 100. If the operation is carried out at a feed of 0.08 mm/rev, the heights of micro irregularities on the machined surfaces (in mm) in the two cases will be
(a) 0.0001, 0.024 (b) 0.002, 0.012
(c) 0.003, 0.024 (d) 0.004, 0.012
