An Atwood’s machine has two objects of mass m₁ = 500 g and m₂ = 510 g, connected by a string of negligible mass that passes over a frictionless pulley (Figure). The pulley is a uniform disk with a mass of 50 g and a radius of 4 cm. The string does not slip on the pulley. 

(a) Find the acceleration of the objects. 

(b) What is the tension in the string supporting m₁? In the string supporting m₂? By how much do they differ? 

(c) What would your answers have been if you had neglected the mass of the pulley?
