A spring scale being used to measure the weight of an object reads 17.1 N when it is used on earth. The spring stretches 4.40 cm under the load. The same object is weighed on the moon, where gravitational acceleration is
Find the reading of the spring scale on the moon.
mg=17.1 N =>
On the moon
x₁=mg`/k =m•1.6•g•x /mg=1.6x=1.6•0.044=0.0704 m
