A) \[2({{F}_{1}}+{{F}_{2}})\]
B) \[{{F}_{1}}+{{F}_{2}}\]
C) \[{{F}_{1}}-{{F}_{2}}\]
D) \[\frac{{{F}_{1}}+{{F}_{2}}}{2}\]
Correct Answer: B
Solution :
Taking torque about O, net torque should be zero. \[{{F}_{2}}\times x-{{F}_{3}}\times x+{{F}_{1}}\times x=0\]You need to login to perform this action.
