A) \[x=f-d,\,\,y=f\,\theta \]
B) \[x=d+f,\,\,y=f\,\theta \]
C) \[x=f-d,\,\,y=-f\theta \]
D) \[x=d-f,\]\[y=-f\,\theta \]
Correct Answer: D
Solution :
From diagram, \[\int_{A}^{B}{{{B}_{P}}dI+}\int_{B}^{C}{{{B}_{P}}di+}\int_{C}^{D}{{{B}_{P}}dI}+\int_{D}^{A}{{{B}_{P}}dI}\] \[+\int_{A}^{B}{{{B}_{Q}}dI+}\int_{B}^{C}{{{B}_{Q}}dI}+\int_{C}^{D}{{{B}_{Q}}dI}+\int_{D}^{A}{{{B}_{Q}}dI}={{\mu }_{0}}\,(2I-I)\]\[(-{{\mu }_{0}}-2{{\mu }_{0}}-{{\mu }_{0}}-2{{\mu }_{0}})\,+(2{{\mu }_{0}}+4{{\mu }_{0}}+2{{\mu }_{0}}+4{{\mu }_{0}})\]\[={{\mu }_{0}}I\] \[\Rightarrow \] \[I=12-6=6A\]You need to login to perform this action.
