Answer:
Resistance = 3.35* Ω
Explanation:
Since resistance R = ρ
whereas
resistivity is given for two ends. At the left end resistivity is whereas x at the left end will be 0 as distance is zero. Thus
At the right end x will be equal to the length of the rod, so
Thus resistance will be R = ρ
where A = π
so,
