What is the magnitude of the acceleration of the masses?
Two masses are connected by a weightless cord, which passes over a frictionless pulley. The masses are held stationary and then released. The acceleration due to gravity is g.

Explanation:
For mass
for mass #m_ 23
assuming the weightless cord is inextensible

g/4
Explanation:
Clearly the 5 kg will go downwards and as a result the cord will try to pull the 3 kg above.
Let tension in cord is T
So,for 5 kg we can write,
For, 3 kg we can write,
Eliminating T from both we get, a=
