defence exam Agniveer Vayu Group X & XY Mock Test 01/2026 Physics Current, Resistance and Electricity Resistance and Resistivity
A rod of a certain metal is \(1.0\ m\) long and \(0.6\ cm\) in diameter. Its resistance is \(3.0\times 10^{-3}\ \Omega\). Another disc made of the same metal is \(2.0\ cm\) in diameter and \(1.0\ mm\) thick. What is the resistance between the round faces of the disc?
1
\(1.35\times 10^{-8}\ \Omega\)
2
\(2.70\times 10^{-7}\ \Omega\)
3
\(4.05\times 10^{-6}\ \Omega\)
4
\(8.10\times 10^{-5}\ \Omega\)
