Ответ:
The net torque will be "1366.33 Nm".
Explanation:
The given values are:
Length of ladder,
then,
Mass,
= 20.3 kg
Now,
The net torque will be:
⇒![\tau_{net}=\tau_{mg}+\tau_{242}](/tpl/images/1315/2354/6cf9f.png)
On putting the given values, we get
⇒![=4.92\times (-mg)+9.83\times (+242)](/tpl/images/1315/2354/0e76e.png)
⇒![=4.92\times (-21\times 9.8)+9.83\times 242](/tpl/images/1315/2354/c3c6d.png)
⇒![=-1012.53+2378.86](/tpl/images/1315/2354/a4043.png)
⇒![=1366.33 \ Nm](/tpl/images/1315/2354/253d3.png)
