this is an assignment in our class , it is required to use 2 NO momentairy switches instead of what is used usually (NC for stop and NO for start ) ? i know it is very primitive question but I am quite the beginner here

Thanks a lot

The answer will depend on what class it is for.

You could use a set/reset flip flop driving a power stage or build something out of discrete bipolar or mosfet transistors. You could also use a pair or relays.

the class is for relays

Thanks for replying ,

I did the first (2 NO switches using 2 relays) but I am stuck at the second task (2 NC switches using 2 relays). every time I try to solve it , I get the load to either constantly on the on mode or constantly on the off mode

Each of the NC switches will be wired in series with one of the relay coils and you will use the NC contacts on each relay to drive the coil of the other.

There will be an unstable startup condition.
