A) 1 : 64
B) 64 : 1
C) 4 : 1
D) 1 : 4
Correct Answer: D
Solution :
\[\frac{{{\sigma }_{small}}}{{{\sigma }_{Big}}}=\frac{q}{Q}\times \frac{{{R}^{2}}}{{{r}^{2}}}=\frac{q}{(nq)}\times \frac{{{({{n}^{1/3}}r)}^{2}}}{{{r}^{2}}}\]\[={{n}^{-1/3}}={{(64)}^{-1/3}}=\frac{1}{4}\]You need to login to perform this action.
