What are two ways that electromagnetic forces and strong nuclear forces are alike and two ways that they are different?

Answer 1

The similarities are related to the type of force interaction (look up the possibilities) and the differences are due to the scale (relative distances between objects) of the two.

Alike:

Both forces act at a distance.
They both involve the exchange of particles.

Different:

Electromagnetic forces act between charged particles, while strong nuclear forces act between nucleons.
Electromagnetic forces have infinite range, while strong nuclear forces are effective only at very short distances within the atomic nucleus.
