A) 1:4
B) 1:3
C) 1:2
D) 1:1
Correct Answer: C
Solution :
Here,\[{{r}_{1}}=10cm,{{q}_{1}}=10\mu \,C,{{r}_{2}}=20cm\] As \[\frac{{{\sigma }_{1}}}{{{\sigma }_{2}}}=\frac{{{r}_{1}}}{{{r}_{2}}}\therefore \frac{{{\sigma }_{1}}}{{{\sigma }_{2}}}=\frac{10}{20}=\frac{1}{2}.\] Hence, the correction option is [c].You need to login to perform this action.
