An astrobiological probe is designed to explore the subsurface ocean of Jupiter's moon Europa. The probe descends through the ice sheet to the ocean water at a depth of 15 km below the surface. The density of this subsurface brine is 1080 kg/m3 and the gravitational field strength on Europa is 1.3 N/kg.
What is the hydrostatic pressure exerted by the ocean fluid on the probe at this depth?
