A) \[10\sqrt{2}\]kg
B) \[2\sqrt{10}\]
C) \[10\,kg\]
D) \[20\,kg\]
Correct Answer: A
Solution :
\[|\overrightarrow{F}|=\sqrt{{{(6)}^{2}}+{{(8)}^{2}}+{{(10)}^{2}}}\] \[\therefore \] \[|\overrightarrow{F}|=\sqrt{36+64+100}\] \[|\overrightarrow{F}|=\sqrt{100+100}=\sqrt{200}\] \[|\overrightarrow{F}|=10\sqrt{2}N\] \[\therefore \] \[m=\frac{|\overrightarrow{F}|}{a}=\frac{10\sqrt{2}}{1}\] \[=10\sqrt{2}\,kg\]You need to login to perform this action.
