There is no African country that is located on both the equator and the Tropic of Capricorn.

* The equator is an imaginary line that circles the Earth at 0 degrees latitude.

* The Tropic of Capricorn is another imaginary line that circles the Earth at 23.5 degrees south latitude.

These lines are parallel to each other, meaning they never intersect. Therefore, no country can be located on both simultaneously.
