A thin rod AB of length 2 m and mass 10 kg is hinged at A and is held in equilibrium, as shown in the given figure, by a horizontal force F acting at B. Which one of the following equations of virtual work will yield value of force F?
1
\(F\delta {y_B} + 10\delta {x_C} = 0\)
2
\(F\delta {y_B} = 10\delta {x_c}\)
3
\(F\delta {x_B} + 10\delta {y_c} = 0\)
4
\(F\delta {y_B} = 10\delta {y_c}\)
