    14 cm

    Step-by-step explanation:

    If three parts have the ratio between their lengths 2:3:5, then the shortest part has the length of 2x cm, the middle part - 3x cm and the longest part - 5x cm.

    Since the longest part is 35 cm, then

    5x=35,

    x=7 cm.

    So, the shortest part is 14 cm long.
