I already have an hemisphere.obj
3D model. But I'm trying to build a half-hemisphere (quarter sphere) model. How can I do that? What is the easiest way to do that?
Generally, is there any easy way to create 1/n of sphere?

If you just need it once, I'd suggest you pick up some basic knowledge of a modelling tool. It's very easy to do in Blender:
DEL
.Create an UV Sphere
primitive. This will create a sphere with radius 1.0
(Note: In the lower left corner you can edit the properties (segment/ring count, radius) of the sphere after creation.)
Press TAB
to enter edit mode. Press a
to clear the selection (which is orange).
Change the display mode to wireframe (so we can select stuff that would be hidden behind the front surface):
Press b
and you'll get a selection rectangle. Select all vertices you want to remove:
Press DEL
and select Vertices
.
For a quarter-sphere: Change view to Top
like in step 3 and repeat steps 6 and 7.
Once you're done editing, hit TAB
to exit edit mode.
Select File -> Export -> Wavefront (.obj)
.
Maya experience here. Use a plane or cube to insect with your object. Use boolean operation like UNION,difference, etc to get this.
