A metal wire of diameter 1 mm is held on two knife edges separated by a distance of 50 cm. The tension in the wire is 100 N. The wire vibrates with its fundamental frequency and a vibrating tuning fork together produce 5 beat/s . The tension in the wire is then reduced to 81 N. When the two are excited , beats are heard at the same rate, then the frequency of the fork will be
