What is the conductivity of a wire of resistance $0.05 \Omega$, area of cross section $2 \times 10^{-4} m^2$ and length 50 cm? |
$5 \times 10^2 \Omega^{-1} m^{-1}$ $5 \times 10^3 \Omega^{-1} m^{-1}$ $5 \times 10^4 \Omega^{-1} m^{-1}$ $5 \times 10^{-3} \Omega^{-1} m^{-1}$ |
$5 \times 10^4 \Omega^{-1} m^{-1}$ |
The correct answer is Option (3) → $5 \times 10^4 \Omega^{-1} m^{-1}$ |
