A wire of mass 15 g is stretched between two points 100 cm apart with tensional force of 35 N. When the wire is plucked, standing waves are formed in the wire. (a) Calculate the fundamental frequency and the third overtone frequency of the wire. (b) If the tensional force of wire is doubled, determine the new fundamental frequency.
