A 20.0-kg mass is supported by two strings as shown in Fig. 12-4. The left string is 2.00 m long and the right string is 5.00 m long. The attachment points for the two strings are 6.00 m apart on the ceiling.
(a) What is the tension in the left side string?
(b) What is the tension in the right side string?
