The correct answer is:
$40 \mathrm{~N}$
The given situation can be shown as
$\text { The tension } T=M_{A} \times a$
here,
$\begin{aligned}
M_{A} &=20 \mathrm{~kg} \text { and } a=2 \mathrm{~ms}^{-2} \\
T &=20 \times 2=40 \mathrm{~N}
\end{aligned}$
$\text { The tension } T=M_{A} \times a$
here,
$\begin{aligned}
M_{A} &=20 \mathrm{~kg} \text { and } a=2 \mathrm{~ms}^{-2} \\
T &=20 \times 2=40 \mathrm{~N}
\end{aligned}$
