A) \[2\sqrt{3}m/{{s}^{2}}\]
B) \[\sqrt{3}m/{{s}^{2}}\]
C) \[3\sqrt{3}m/{{s}^{2}}\]
D) \[4\sqrt{3}m/{{s}^{2}}\]
Correct Answer: B
Solution :
\[{{F}_{net}}=\sqrt{F_{1}^{2}+F_{2}^{2}+2{{F}_{1}}{{F}_{2}}\cos \theta }\] \[=\sqrt{{{(10)}^{2}}+{{(10)}^{2}}+2\times 10\times 10\times \cos {{60}^{o}}}\] \[=\sqrt{100+100+100}\] \[=10\sqrt{3}\] Mass of the body = 10 kg \[\therefore \] \[Acceleration=\frac{force}{mass}\] \[=\frac{10\sqrt{3}}{10}\] \[=\sqrt{3}m/{{s}^{2}}\]
