A) 1 : 10
B) 10 : 1
C) 1 : 100
D) 100 : 1
Correct Answer: C
Solution :
\[I=\frac{L}{{{r}^{2}}}\]\[\Rightarrow \frac{{{L}_{1}}}{r_{1}^{2}}=\frac{{{L}_{2}}}{r_{2}^{2}}\] (I is same) \[\Rightarrow \frac{{{L}_{1}}}{{{L}_{2}}}=\frac{r_{1}^{2}}{r_{2}^{2}}={{\left( \frac{1}{10} \right)}^{2}}=1:100\].You need to login to perform this action.
