A) 3.25 V
B) 2.5 V
C) 2.25 V
D) 2 V
Correct Answer: C
Solution :
Given \[{{l}_{1}}=35\,cm,\,\,{{l}_{2}}=63\,cm\] \[{{E}_{1}}=1.25\,V;{{E}_{2}}=?\] \[\therefore \] \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{{{l}_{1}}}{{{l}_{2}}}\] \[{{E}_{2}}=\frac{{{l}_{2}}}{{{l}_{1}}}\times {{E}_{1}}\] \[=\frac{63}{35}\times 1.25\] = 2.25 VYou need to login to perform this action.
