I presume you mean put it in the gasoline tank?

If the motor was already warm, it might continue to run. However, it
wouldn't restart if cold. You'd have to drain out the diesel and replace
with gasoline to get it running again.

No major damage.

If one were to mistakenly put diesel fuel into a lawn mower that would
normally require gasoline, what would be the result?
