A) 6.5 A/rad
B) 7.6 A/rad
C) 7.5 A/rad
D) 8.0 A/rad
Correct Answer: B
Solution :
Here \[I=4A\] \[\theta ={{30}^{o}}={{\left( \frac{30\times \pi }{180} \right)}^{c}}=\frac{\pi c}{6}\] Now, \[k=\frac{I}{\theta }=\frac{4}{\left( \frac{\pi }{6} \right)}=\frac{4\times 6\times 7}{22}=\frac{2\times 6\times 7}{11}\] \[=\frac{84}{11}=7.6\text{A/rad}\]
