An underground cable of length 100 meters has insulation of relative permittivity 4. If the conductor diameter and inner sheath diameter of the cable is 3 cm and 9.5 cm, respectively, then find the capacitance of the cable.
1
\(\frac{4}{41.4 \log_{10}3.167} \times 10^{-9}F\)
2
\(\frac{200}{41.4 \log_{10}3.167} \times 10^{-9}F\)
3
\(\frac{400}{41.4 \log_{10}3.167} \times 10^{-9}F\)
4
\(\frac{100}{41.4 \log_{10}3.167} \times 10^{-9}F\)
