Hi, the question is in the screenshot. I can't copy the questions as it contains some symbols. However, I would appreciate some help with this in details. It's multivariable calculus: Surface Integrals.

3) A point mass m is located at the origin. Let F = -m (x, y, z) (where p2 = x2 + y2 + z2) be its gravitational field. Let Q be the flux of the gravitational field F through the cylinder x2 + y2 = R2 for a 0 or a
