Homework Statement
A pulley system is hanging from a Newton meter as shown below. If we assume that gravitational acceleration is [tex]10 m/s^{2}[/tex], what will the reading be on the Newton meter as the masses accelerate?
a) 3 Kg
b) 13 N
c) 27 N
d) 30 N

The Attempt at a Solution
I think that the answer is d), because if you add the masses of the two objects, which turns out to be 3.0 Kg, and multiply that by the gravitational acceleration, you would get 30 N. Am I right?
