Question

8.
There are two wires of the same length and of the
same material and radius r and 2r. The ratio of
their specific resistance is
(1) 1:2
(2) 1:1
(3) 1:4
(4) 4 : 1
​

Answer 1

the answer is (2) 1:1 because they are made up of same material specific resistance doesn't change with the dimensions of the resistor.
