Two spheres of radii $1 \, cm$ and $2 \, cm$ are charged with $1.5 \times 10^{-8} \, C$ and $0.3 \times 10^{-7} \, C$ of positive charge,respectively. When they are connected by a wire,the charge will flow:

  • A
    From the first sphere to the second sphere
  • B
    From the second sphere to the first sphere
  • C
    Will not flow
  • D
    From the first to the second or from the second to the first
