Question

Two blocks m₁ = 5 gm and m₂ = 10 gm are hung
vertically over a light frictionless pulley as shown
here. What is the acceleration of the masses when
they are left free?
(a) g / 3 (b) g / 2
(c) g (d) g / 5

Answer 1

Answer:

acceleration a =g(m2-m1)/m1+m2

                        =g(5/10)

                        =g/2
