Has as Assignment. A Spiral Spring of
ma natural length 20cm
scale pan hanging freely in its
lower and when an object of mass
Log is placed in the pan: it's length
becames 21.80cm. When another
object of mass 60g is placed in the
pan, the length becomes 22.06cm.
calculate the mass of the scalepan .

10 newton object is placed 3 meters from the fulcrum. at what distance on the other side would you need to place a 15 newton object to balance the lever? show your work!
