A 12.0 kg object hangs in equilibrium from a string with a total length of L= 5.0 m and a linear mass density of mu (micro) =0.001 kg/m. The string is wrapped around two light, frictionless pulleys that are separated by a distance of d=2.0 m. a) Determine the tension in the string. b) At what frequency must the string between the pulleys vibrate to form the standing-wave pattern as shown? ANS a) T=80.5 N b) f=212.8 Hz
