1.	There is an infinite thin flat sheet with mass density eta per unit area. Find the gravitational force, due to sheet, on a point mass m located at a distance x from the sheet.Consider a large flat horizontal sheet of material density r and thickness t, placed on the surface of the earth. The densityphiof the earth is phi_(0) If it is found thatravitational field intensity just between the sheet is larger than field just above it, prove that rho_(@)lt(3)/(2)rho.
