\textbf{160-} In the figure below, if the pulley and strings are massless and frictionless, the tension $T$ is how many Newtons? $\left(g = 10\,\dfrac{\text{m}}{\text{s}^2}\right)$
\textit{[Figure: A fixed pulley attached to ceiling with a string over it; tension $T$ shown at top; two masses $4\,\text{kg}$ and $1\,\text{kg}$ hanging on either side]}
