The resistance of a wire is ${10^{ - 6}}\,\Omega $ per meter. It is bend in the form of a circle of diameter $2\,m$. A wire of the same material is connected across its diameter. The total resistance across its diameter $AB$ will be
  • A$\frac{4}{3}\pi \times {10^{ - 6}}\,\Omega $
  • B$\frac{2}{3}\pi \times {10^{ - 6}}\,\Omega $
  • C$0.88 \times {10^{ - 6}}\,\Omega $
  • D$14\pi \times {10^{ - 6}}\,\Omega $
