Two metallic spheres of radii $1\,cm$ and $2\,cm$ are given charges ${10^{ - 2}}\,C$ and $5 \times {10^{ - 2}}\,C$ respectively. If they are connected by a conducting wire, the final charge on the smaller sphere is
  • A$3 \times {10^{ - 2}}\,C$
  • B$1 \times {10^{ - 2}}\,C$
  • C$4 \times {10^{ - 2}}\,C$
  • D$2 \times {10^{ - 2}}\,C$
