Answer:
R' = R/4
Explanation:
The resistance of a metal rod is R. It is given by the relation as follows :
Where
l is the length and A is the area of cross-section
If both its length and its diameter are quadrupled, it means,
l' = 4l
and d'= 4d
It means,
Let new resistance be R'. So,
So, the correct option is (B) "R/4".
