Problem P. 4464. (September 2012)

P. 4464. A certain type of alpha-radiation can penetrate to a depth of 4 cm to a sample of air at a pressure of 105 Pa. To what depth would it penetrate into a sample of less dense air at a pressure of 103 Pa? (The \alpha-particle -- being a ``heavy'' particle -- hardly changes its direction while it interacts with the atoms, so its path is approximately a straight line.)
