Two objects of unequal masses are hung vertically over a frictionless pulley of negligible mass, as shown in the Figure. The arrangement is called Atwood's Machine. If m2 = 2m1 then the magnitude of the acceleration of the two objects equals
a) (m2 - m1)g/(2m2 + m1)
b) 2(m2 - m1)g/(m2 + m1)
c) g/2
d) g/3
