Coarse grains are good for higher material removal rate and are suitable for the soft ductile material.
Fine grain take a small depth of cut provide better surface finish, generate less heat, i.e. these are use for hard brittle material

Rough grinding - coarse wheel.
Finish grinding - finer wheel.
Hard work piece - soft grinding wheel.
Soft work piece - hard grinding wheel.
Finish grinding - finer wheel.
Hard work piece - soft grinding wheel.
Soft work piece - hard grinding wheel.

For hard materials it's required more strength for grains. So we use fine grain.

Coarse grained abrasive are used for fast removal of materials and fine grained wheel are used for finish of work. Coarse grained for grinding soft materials and fine grained for hard and brittle materials.

But it should be depend on the surface finishing required right?

Course grinding: Soft material.
Fine grinding: Hard material.
Fine grinding: Hard material.

Fine grains are arranged very nearly so their hardness is too high so it is used for hard material cutting.

Maybe because for fine-grained wheel there are more number of cutting edges.

How does the force required to grind the surface relate to the grain size?

Grain size is selected based on the surface finish to be produced on the work piece for rough grinding coarse and medium, for finishing very fine grains are used.
