A planet has radius `((1)/(36))` th of the radius of the earth. The escape velocity on the surface of the planet was found to be `(1)/(sqrt(6))` times the escape velocity from the surface of e earth. The planet is surrounded by a thin layer of atmosphere having thickness h (ltlt radius of the planet). The average density of the atmosphere on the planet is d and cceleration due to gravity on the surface of the earth is `g_(e)`. Find the value of atmospheric pressure on the surface of the planet.
