A) 2 N
B) 4 N
C) 6 N
D) 8 N
Correct Answer: C
Solution :
The total torque about\[O\]is given by or \[\tau ={{F}_{1}}d+{{F}_{2}}d-{{F}_{3}}d\] \[\Rightarrow \] \[{{F}_{3}}={{F}_{1}}+{{F}_{2}}\] \[=4+2\] \[=6N\] Here, d is the perpendicular distance of\[O\]from every side of the equilateral triangle.You need to login to perform this action.
