Two masses M1 = 5 kg and M2 = 10 kg are connected at the ends of an inextensible string passing over a frictionless pulley as shown. When the masses are released, then the acceleration of the masses will be:
(where 'g' is acceleration due to gravity)

(A) g                  (B) g/2                   (C) g/3              (D) g/4

Dear Student,
                      We have acceleration of the masse =net force total mass=5g15=g/3
