A 12.0-kg object hangs in equilibrium

A 12.0-kg object hangs in equilibrium from a string with a total length of L = 5.00 m and a linear mass density of Âľ = 0.001 00 kg/m. The string is wrapped around two light, frictionless pulleys that are separated by a distance of d = 2.00 m (Fig. P18.69a)
(a) Determine the tension in the string.
