Problem 11P
Two strings are made of the same material and have waves of equal speed. String 1 is thick; string 2 is thin, (a) Is the tension in string 1 greater than, less than, or equal to the tension in string 2? (b) Choose the best explanation from among the following:
I. String 1 must have a greater tension to compensate for its greater mass per length.
II. String 2 will have a greater tension because it is thinner than string 1.
III. Equal wave speeds implies equal tensions.
