    Rohan falls on the ground by banana peel because : 1. the surface of the banana peel is smooth which reduces the friction between his foot and ground . 2. the irregularities of the surface was filled up by the banana peel making it more fiction less.

    Investigation Result - Rohan fell because when he stepped over the banana peel the friction between the banana peel and the surface became less because the banana peel has a smooth surface.

    So the result of the investigation is- Rohan slept because he stepped on the banana peel ,banana peel make the rough Road smooth by filling the small irregularities on the road. There fore there is less friction and he fell . Thank you very much sir
