A) \[90{}^\circ and 180{}^\circ \]
B) \[0{}^\circ and90{}^\circ \]
C) \[90{}^\circ and 0{}^\circ \]
D) \[0{}^\circ and 180{}^\circ \]
Correct Answer: D
Solution :
\[\operatorname{V}=\frac{K P Cos\theta }{\operatorname{r}}\] \[\operatorname{V}\propto Cos\theta \] \[{{\operatorname{V}}_{max}}\operatorname{at}\theta ={{0}^{\operatorname{o}}}\] \[{{\operatorname{V}}_{min}}\operatorname{at}\theta ={{180}^{\operatorname{o}}}\]
