Solution 11.4a
From Mechanics
The total weight is
\displaystyle (5+1)g=6\times 9\textrm{.}81=58\textrm{.}8\ \text{N}
Applying the equation of motion with \displaystyle a=0\textrm{.}2\ \text{m}{{\text{s}}^{-2}}
\displaystyle \begin{align}
& \uparrow \ T-58\textrm{.}8=ma=(5+1)\times 0\textrm{.}2=1\textrm{.}2 \\
& \\
& T=58\textrm{.}8+1\textrm{.}2=60\ \text{N} \\
\end{align}
