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