    Explanation:

    Hey there!!

    Let’s simply work with it.

    Here,

    load = 1200N

    Effort = 200N

    Load distance = 15cm

    We have,

    According to the principle of lever.

    L×LD = E×ED.

    1200×15 = 200× ED.

    18000 = 200ED.

    ed = \frac{18000}{200}

    Therefore, Effort Distance = 90cm.

    Hope it helps....
