A) \[\frac{1}{4}\]
B) \[\frac{1}{6}\]
C) \[\frac{1}{8}\]
D) \[\frac{1}{16}\]
Correct Answer: D
Solution :
[d] \[R=\rho \frac{a}{\Alpha }\] and \[{{R}^{'}}=\rho \frac{{{l}^{'}}}{{{\Alpha }^{'}}}\] Here \[{{1}^{'}}=\frac{1}{4}\]and \[{{A}^{'}}=4A\] \[\therefore \,\,\,{{R}^{'}}=\rho \frac{l/4}{4A}=\frac{1}{16}\,\,\rho \frac{1}{A}=R/16\]You need to login to perform this action.
