An air bubble of radius $r$ in water is at depth $h$ below the water surface. If $P$ is the atmospheric pressure, and $d$ and $T$ are the density and surface tension of water respectively, then the pressure inside the bubble will be:

  • A
    $P + hdg - (4T/r)$
  • B
    $P + hdg + (2T/r)$
  • C
    $P + hdg - (2T/r)$
  • D
    $P + hdg + (4T/r)$
