```							we have got two equations here:1st eq. is-l1 + e = v/4f.........(1)2nd eq.isl2 + e = 3v/4f........(2)Apply (2) – (1)l2 - l1 = 3v/4f – v/4f = 2v/4f = v/2fdelta(l2 - l1) / (l2 - l1) = delta(v) / vdelta(v) = 2f delta(l2 - l1) = 2f(deltal1 + deltal2) …......for maximum errordelta(v) = 2 x 512 x (0.1 + 0.1) = 2 x 512 x 0.2delta(v) = 204.8 cm/sHence (c) is correct.
