Number 10.34. 10.35 . Please help me

cylindrical shell of radius R and mass M. 10.34. By using Gauss's law, calculate the gravitational field intensity at a distance x from an infinitely long cylindrical rod of mass density o per unit length. 10.35. Show that if we consider a mass M outside an enclosed surface, then the net flux through this sur- face is zero. 10.36. Show that the equations V x g = 0, V g = -4TGP, and VV = 4mGp are all satisfied by the %3D %3D | gravitational field intensity and gravitational potential in Problems 10.30 and 10.31
